          ACTIVE POWER FILTER BASED ON CASCADED
            TRANSFORMER MULTILEVEL INVERTER

ABSTRACT :

       The widespread increase of non-linear loads nowadays, significant amounts of harmonic
currents are being injected into power systems. Harmonic currents flow through the power
system impedance, causing voltage distortion at the harmonic currents’ frequencies. The
distorted voltage waveform causes harmonic currents to be drawn by other loads connected at the
point of common coupling (PCC).
        The use of grid connected power electronic converters to improve power quality in
power distribution systems represents the best solution, in terms of performance and stability, for
the elimination of harmonic distortion, power factor correction, balancing of loads, and voltage
regulation. The traditional method of current harmonics reduction involves passive LC filters,
which are its simplicity and low cost. However, passive filters have several drawbacks such as
large size, tuning and risk of resonance problems
        In this project, we propose an APF based on cascaded H-bridge multilevel converter
which employs one single dc input power source and isolated single-phase low-frequency
transformers. By the proposed circuit configuration, a number of dc-link can be reduced,
compared with traditional APF based on cascaded H-bridge multilevel converter. With this type
of topology, higher voltage levels can be achieved, making the proposed topology suitable for
compensation of medium and high voltage power distribution systems. A simple control scheme
is used for the correct operation of inverter and compensation demands. The current reference
required can be obtained allowing the generation of the total compensating current and the
absorption of the needed active power to compensate converter losses and to keep the dc
voltages constant. Simulated results carried out by MATLAB/Simulink program for steady-state

        A PRACTICAL TECHNIQUE FOR POWER QUALITY
        IMPROVEMENT FOR SINGLE PHASE INDUCTION
                       MACHINES

ABSTRACT :

       Most of the electrical loads in our daily life are single phase as well as inductive. Single
phase induction machines are one of the many reasons for poor quality power supply along with
some concerns on torque requirements, accelerating time, starting current, and dip in voltage and
harmonics in input current. During starting, power supply is more adversely affected.
        When single motors at homes are started, a visible fluctuation in lights is observed. This
is due to the poor quality of power during starting of single phase induction motor. When the
motor is started, it draws high starting current. This high current cause’s dip in the voltage during
starting intervals, because there is a lot of voltage drop across the distribution conductor.
        This project presents an analysis of all the above mentioned problems along with a
practical way to mitigate them. In this project, induction motor under test is the capacitor run
motor. In this project a practical approach is presented using classical LC circuit techniques.
The results and tests performed before and after application of the proposed solution have been
analyzed and presented. The frequency, running current waveform current components in time
domain are simulated using MATLAB/Simulink software, The conclusions presented in this

       Multilevel voltage-source inverters are intensively studied for high-power applications

pointed out the limitations of conventional inverters, especially in high-voltage and high-power
applications.
       In recent years, multilevel inverters are becoming increasingly popular for high-power
applications due to their improved harmonic profile and increased power ratings. Several studies
have been reported in the literature on multilevel inverters topologies, control techniques, and
applications. However, there are few studies that actually discuss or evaluate the performance of
induction motor drives associated with three-phase multilevel inverter.
       This project presents then a comparison study for a cascaded H-bridge multilevel direct
torque control (DTC) induction motor drive. In this case, symmetrical and asymmetrical
arrangements of five- and seven-level H-bridge inverters are compared in order to find an
optimum arrangement with lower switching losses and optimized output voltage quality.
        For the validation of the earlier discussed control approach, simulations and experiments
have been carried out. The carried out experiments show that an asymmetrical configuration
provides nearly sinusoidal voltages with very low distortion, using less switching devices.
Moreover, torque ripples are greatly reduced. Simulation results for five levels cascaded and

    A DYNAMIC VOLTAGE RESTORER EQUIPPED WITH A
     HIGH-FREQUENCY ISOLATED DC–DC CONVERTER

ABSTRACT :

       This project presents a dynamic voltage restorer (DVR) that is characterized by the use of
a high-frequency unidirectional isolated dc–dc converter. Voltage sag is the most power quality
problem facing now days in distribution system; this project discusses the control and
performance of a low-voltage DVR using a high-frequency isolated dc–dc converter. The high-
frequency (20-kHz) transformer in the dc–dc converter is much smaller, for example, one-
hundredth, in volume than the line-frequency transformer. DVR, which is characterized by
connecting the shunt converter (the diode rectifier) to the supply side.
        The DVR consists of shunt and series converters connected back to back and a common
dc capacitor as an energy-storage device. Multilevel topologies such as diode-clamped or
cascaded pulse width modulation (PWM) converters can eliminate line frequency transformers
from medium-voltage applications,
       A main motivation of the isolated dc–dc converters is to replace line-frequency
transformers with high-frequency transformers, in which galvanic isolation is indispensable
between the two sets of dc terminals; Experimental results obtained by a 200-V 5-kW laboratory
system have verified the viability and effectiveness of the DVR. In the near future, replacing Si
devices with SiC devices will bring significant reductions in volume and weight to the dc–dc
converter,   as   well    as   the   series   converter.   Simulation      has   been   done   using
MATLAB/SIMULINK software.

  A HYBRID AC/DC MICRO GRID AND ITS COORDINATION
                     CONTROL

ABSTRACT :

       THREE PHASE ac power systems have existed for over 100 years due to their efficient
transformation of ac power at different voltage levels and over long distance as well as the
inherent characteristic from fossil energy driven rotating machines. Recently more renewable
power conversion systems are connected in low voltage ac distribution systems as distributed
generators or ac micro grids due to environmental issues caused by conventional fossil fueled
power plants. Recently dc grids are resurging due to the development and deployment of
renewable dc power sources and their inherent advantage for dc loads in commercial, industrial
and residential applications, the dc micro grid has been proposed to integrate various distributed
generators. However, ac sources have to be converted into dc before connected to a dc grid and
dc/ac inverters are required for conventional ac loads.
       This project proposes a hybrid ac/dc micro grid to reduce the processes of multiple dc–
ac–dc or ac–dc–ac conversions in an individual ac or dc grid. The hybrid grid consists of both ac
and dc networks connected together by multi-bidirectional converters. AC sources and loads are
connected to the ac network whereas dc sources and loads are tied to the dc network. Energy
storage systems can be connected to dc or ac links. The proposed hybrid grid can operate in a
grid-tied or autonomous mode. The coordination control algorithms are proposed for smooth

power transfer between ac and dc links and for stable system operation under various generation
and load conditions. Uncertainty and intermittent characteristics of wind speed, solar irradiation
level, ambient temperature, and load are also considered in system control and operation.
        A small hybrid grid has been modeled and simulated using the Simulink in the
MATLAB. The simulation results show that the system can maintain stable operation under the
proposed coordination control schemes when the grid is switched from one operating condition
to another.




  A MODIFIED C-DUMP CONVERTER FOR BLDC MACHINE
    USED IN A FLYWHEEL ENERGY STORAGE SYSTEM

ABSTRACT :

       The permanent magnet brushless DC machine (BLDCM) is one of the suitable motors for
the flywheel energy storage system (FESS) The common half-bridge topology for high-speed
BLDCM. It includes a buck chopper and a half-bridge converter. Compared with the full-bridge
converter, the half bridge converter has half the number of switches and avoids the short circuit
across the phase leg in the full-bridge converter.
       However, this half-bridge topology has two disadvantages for the FESS: 1) the energy
unidirectional flow, and 2) the energy of the turnoff phase is consumed on the resistance which
means the waste of energy.
       This project presents a modified C-dump converter for brushless DC (BLDC) machine
used in the flywheel energy storage system. The converter can realize the energy bidirectional

flowing and has the capability to recover the energy extracted from the turnoff phase of the
BLDC machine. The principle of operation, modeling, and control strategy of the system has
been investigated in the paper. Simulation and experimental results of the proposed system are
also presented and discussed.




  A MINIMUM POWER-PROCESSING-STAGE FUEL-CELL
 ENERGY SYSTEM BASED ON A BOOST-INVERTER WITH A
     BIDIRECTIONAL BACKUP BATTERY STORAGE

ABSTRACT :

       When low-voltage unregulated fuel-cell (FC) output is conditioned to generate ac power,
two stages are required: a boost stage and an inversion one. A two-stage FC power conditioning
system to deliver ac power has been commonly considered and studied. The system usually
includes transformer-type dc–dc boost converter stage and dc-to-ac inverter stage with auxiliary
energy unit. This type of power conditioning system has inevitable drawbacks, such as being
bulky, costly, and inefficient, because each stage has to have a high efficiency for higher overall
efficiency and normally more than six active components (switches and diodes) are required.
       In order to minimize the problems with a two-stage FC power conditioning system, a
topology with reduced power processing and conversion stages is required. A topology that is

suitable for ac loads and is powered from dc sources able to boost and invert the voltage at the
same time has been proposed. The double-loop control scheme of this topology has also been
proposed for better performance, even during transient conditions.
        In this paper, the boost-inverter topology that achieves both boosting and inversion
functions in a single stage is used to develop an FC-based energy system that offers high
conversion efficiency, low-cost, and compactness. The proposed system incorporates additional
battery-based energy storage and a dc–dc bidirectional converter to support instantaneous load
changes. The output voltage of the boost-inverter is voltage-mode controlled and the dc–dc
bidirectional converter is current-mode controlled. The load low-frequency current ripple is
supplied by the battery, which minimizes the effects of such ripple being drawn directly from the
FC itself. Analysis, simulation, and experimental results are presented to confirm the operational
performance of the proposed system.

ABSTRACT :

       The dynamic voltage restorer (DVR) is one of the modern devices used in distribution
systems to protect consumers against sudden changes in voltage amplitude. In this project,
emergency control in distribution systems is discussed by using the proposed multifunctional

controllers is proposed in order to improve the transient response and eliminate the steady-state
error in DVR response, respectively.
       The main purpose is to detect and compensate for the voltage sag with minimum DVR
active power injection. Also, the in-phase compensation method can be used for sag and swell
mitigation. The multiline DVR can be used for eliminating the battery in the DVR structure and
controlling more than one line. Moreover, research has been made on using the DVR in medium
level voltage. Harmonic mitigation and control of DVR under frequency variations are also in
the area of research. The closed-loop control with load voltage and current feedback is
introduced as a simple method to control the DVR.
       The proposed algorithm is applied to some disturbances in load voltage caused by
induction motors starting, and a three-phase short circuit fault. Also, the capability of the
proposed DVR has been tested to limit the downstream fault current. The current limitation will
restore the point of common coupling (PCC) (the bus to which all feeders under study are
connected) voltage and protect the DVR itself. The innovation here is that the DVR acts as a
virtual impedance with the main aim of protecting the PCC voltage during downstream fault
without any problem in real power injection into the DVR.
       The basis of the proposed control strategy in this project is that when the fault current
does not pass through the DVR, an outer feedback loop of the load voltage with an inner
feedback loop of the filter capacitor current will be used. Also, a feed forward loop will be used
to improve the dynamic response of the load voltage. Moreover, to improve the transient
response, the Posicast controller and to eliminate the steady-state error. Simulation results show
the capability of the DVR.

       There are three basic types of AC to AC converters. The simplest ones, the AC voltage
controllers, allow controlling the output voltage only, while the output frequency is the same as
the input frequency. The second one is the Cycloconverters. In Cycloconverters, the output
frequency can be controlled, but it is at least one order of magnitude lower than the input
frequency. In both the AC voltage controllers and Cycloconverters, the maximum available
output voltage approaches the input voltage. The last one is the matrix converter. Because of
having no inherent limits on the output frequency, matrix converters are most versatile, but the
maximum available output voltage is about 15% lower than the input voltage AC voltage
controllers are widely used to obtain variable AC voltage from fixed AC source.
       A lot of topologies of pulse-width modulated (PWM)-AC voltage controllers for single-
phase and three phase systems are proposed up to date. PWM-AC controllers have important
advantages compared with the phase-controlled AC voltage controllers using Thyristors and
Triacs. This project presents a novel control technique for application to PWM-AC controllers
with ability of generating smaller harmonics. In the proposed control method, both the traditional
AC voltage controllers and the PWMAC controllers are combined, smaller THD values are
obtained and switching losses are minimized. Thus, the harmonic pollution in the power system
will be reduced and the power quality will be increased.
       In order to investigate the proposed controller performance, computer simulations are
performed. Obtained results are compared with those of the conventional PWM-AC controller
According to the simulation sector-control with PWM method has better performance than
phase-angle control with PWM method does. So, sector-control with PWM method is
recommended to the power community. This method can be of practical value in replacing the
conventional counterparts that are used in controlling heating elements and speed control of
small fractional horsepower induction motors. Simulation results are conducted using
MATLAB/SIMULINK software.

      A NEW MULTILEVEL INVERTER TOPOLOGY USING
              LESS NUMBER OF SWITCHES
ABSTRACT :

       Multilevel voltage source inverter is recognized as an important alternative to the normal
two level voltage source inverter especially in high voltage application. Using multilevel
technique, the amplitude of the voltage is increased, stress in the switching devices is reduced
and the overall harmonics profile is improved. Among the familiar topologies, the most popular
one is cascaded multilevel inverter. It exhibits several attractive features such as simple circuit
layout, less components counts, modular in structure and avoid unbalance capacitor voltage
problem. However as the number of output level increases, the circuit becomes bulky due to the
increase in the number of power devices, the general purpose of the multilevel inverter is to
synthesize a nearly sinusoidal voltage from several levels of dc voltages, typically obtained from
capacitor voltage sources. As the number of level increases, the synthesized output waveform
has more steps, which produce a staircase wave that approaches a desired waveform. Also as
more steps added to the waveform, the harmonic distortion of the output waveform decreases,
approaching zero as the level increases. As the number of level increases, the voltage that can be
summing multiple voltage levels also increases.
       These new types of converters are suitable for high voltage and high power application
due to their ability to synthesize waveforms with better harmonic spectrum. Numerous
topologies have been introduced and widely studied for utility and drive applications. Amongst
these topologies, the multilevel cascaded inverter was introduced in Static VAR compensation
and drive systems. This project presents a new technique for getting a multilevel output and also
uses PWM control techniques. In this technique, the number of switches used for the dc to ac
conversion is reduced. So this dc to ac conversion significantly reduces the initial cost. This
technique    exhibits    some   attractive   features   which    suits   industrial   applications.
MATLAB/Simulink environment is used to simulate the results.

        The simulation of the seven-level multilevel inverter is successfully done using pulse
width modulation technique. From the simulation, it is noted that the new multilevel inverter
topology works well and shows hope to reduce the initial cost and complexity. When we increase
the levels, the number of switches used is very less compared to the other topology.

      A NOVEL APPROACH IN SOFT STARTING OF LARGE
                  INDUCTION MOTORS
ABSTRACT :

        The electric power consumption of AC motor is a great part of the total domestic consumption.
So, high efficiency and stability of AC motor can realize energy-saving and cost reducing effectively. Not
only AC motor need to be soft-started to lessen current surge and electric fence voltage-drop, but also its
speed need to be able to adjusted to improve efficiency. If the induction motor is started directly, its
starting current will be up to 5-8 times the rated value, which causes a sharp decline in voltage of the
connecting power network, affecting normal operation of other equipments and causing a great impact on
the motor, especially on cage-type rotor whose bars and rings would be destroyed enormously.
        As the development of the power electronics technology, computer control technology and
automatic control technology, electronic soft-start controller has appeared, while in generally, the starters
on the market only have basic modes such as current-limited and voltage step ramping soft-start.
Although it can meet the demands of most kinds of loads, the start state is not optimal, direct online
induction machine starts have many disadvantages. Torque pulsations are often large and vary from
positive to negative values. These torque transients in a motor shaft are transmitted to the load, resulting
in mechanical wear in the motor bearings and load couplings. Therefore, properly controlling the starting
currents and torques of induction machines is of great importance in many instances.
        This project proposes a new series compensator based circuit for soft starting of IM. This circuit
consists of a diode-bridge type DC reactor that connects in series with each phase of transformer. It does
not need any control, measurement and gate driving circuits. The power circuit simplicity, reliable
operation and almost no effect on normal operation of IM are other advantages of proposed circuit. The
theoretical analysis and the effect on voltage quality are presented. The proposed circuit consists of three

similar diode-bridges and a single coil that each connects in series with each-phase of induction motor.
This circuit has almost no effect in normal operation of induction motors. The simplicity of proposed
circuit, easy to build and absence of control circuits are the main attractive points of circuit. The
analytical analysis and designing characteristics for DC reactor in proposed circuit are presented.
        The overall circuit operation in transient and steady state cases are studied in detail. Simulation
results are obtained to verify the valuable operation of proposed circuit in soft starting. The simulation
results are obtained to verify the performance of proposed method in transient and steady states.




   A NOVEL BVC-RBF NEURAL NETWORK BASED SYSTEM
    SIMULATION MODEL FOR SWITCHED RELUCTANCE
                      MOTOR
ABSTRACT :

        THE switched reluctance motor (SRM) drive is considered as an attractive candidate for
variable speed motor drives due to its low cost and rugged structure, reliable converter topology,
and high efficiency over a wide speed range, and fault-tolerant performance. These drives are
suitable for applications such as electric vehicles, aircraft starter/generator systems, mining
drives, robotics, and. On the one hand, several approaches have been reported in the literature for
obtaining and describing the flux linkage characteristics of SRM, FEA is the most commonly
used method for calculating the flux linkage characteristics without experimental measurement,
which is quite suitable for machine design and performance prediction.
        Nevertheless, almost all of the aforementioned intelligent approximation methods such as
ANN, ANFIS, and RBF are conditioned on that the model is determined based on the
observational data only. But in the modeling task, there is more or less some prior knowledge
available, which can help to improve the model generalization. A new topology of RBF neural

network with boundary value constraints that has the capability of automatically satisfying types
of prior knowledge is proposed, without adding algorithmic complexity and computational costs.
The so-called BVC-RBF neural network is applied to modeling of the flux linkage characteristic
in this project.
         The purpose of this project is to develop a SRM system simulation model considering the
critical problems as discussed above. In this projetc, a double scalar magnetic potential method
(DSMP) based 3-D FEM together with enhanced incremental energy method (EIEM) is used for
flux linkage calculation, which considers the end effect and reduces the computation time. In
order to get better approximation results, a novel BVC-RBF neural network is applied for
modeling of the flux linkage characteristics. Based on the modeling results, a SRM system
simulation model is studied here using MATLAB/Simulink. All simulations are completely
documented by their blocks, corresponding special MATLAB functions, and parameters.

ABSTRACT :

         THE capability of multilevel inverters to generate voltage waveform with less harmonic distortion, at
reduced switching frequency, using switching devices of low-voltage ratings makes them preferred choice for
medium- and high voltage power processing applications. This has led to their increasing applications in the control
of medium and high voltage ac drives .Though with increase in number of levels the quality of waveform improves,
it also increases the complexity of the circuit due to the increase in the number of devices and associated control
circuitry. The other issues of concern in industrial applications are reliability and efficiency of the system. Hence,
the researchers in this field are focused mainly on the development of less complex, more reliable and efficient
multilevel inverter topologies. A survey of multilevel inverter topologies is presented. The conventional multilevel
converters include the neutral point clamped (NPC), flying capacitor, and cascaded H-bridge topologies. Dual
inverter configuration for an open-end winding induction motor is another interesting multilevel topology for drive
applications.

winding structure. Here, in addition to two two-level inverters feeding the coils from both ends, two H-bridge cells
are connected in series with the motor winding in each phase. These H-bridge cells are fed by capacitors whose
voltages are maintained at the required level. An important advantage of this topology is the reduction in dc-link
voltage requirement by half when compared with the requirement of dc-link voltage in NPC topology. In this
topology, there are multiple ways of generating middle voltage levels and this feature is utilized in balancing the
capacitor voltages in the entire modulation range. It needs only two isolated dc-voltage sources of voltage rating Vdc
/2 where Vdc is the dc voltage magnitude required by the conventional neutral point clamped (NPC) seven-level
topology. The proposed topology is capable of maintaining the H-bridge capacitor voltages at the required level of
Vdc /6 under all operating conditions, covering the entire linear modulation and over modulation regions, by making
use of the switching state redundancies.
          In the event of any switch failure in H-bridges, this inverter can operate in three-level mode, a feature that
enhances the reliability of the drive system. The two level inverters, which operate at a higher voltage level of Vdc
/2, switch less compared to the H-bridges, which operate at a lower voltage level of Vdc /6, resulting in switching
loss reduction. The experimental verification of the proposed topology is carried out for the entire modulation range,
under steady state as well as transient conditions.

         Simulation results are studied using MATLAB/SIMULINK software.

between multiple voltage levels. The two most common multilevel inverter topologies are the
diode clamped inverter and the cascaded inverter. In the paper, we will discuss about the
cascaded multilevelinverter. The cascaded multilevel inverter uses series strings of single phase
full bridge inverter to construct multilevel phase legs. A particular advantage of this topology is
that the modulation, control and protection requirement of each bridge are modular. Moreover,
multilevel inverter topologies are able to generate better output quality, while operating at lower
switching frequency. This implies lower switching dissipation and higher efficiency. In this
paper, the conventional PWM inverter and the cascaded multilevel PWMinverter is modeled in
MATLAB Simulink. The analysis of the conventional PWM inverter and the cascaded multilevel
PWMinverter using unipolar and bipolar switching schemes is done and finally the results are
compared.

ABSTRACT :


       This paper presents a new topology of three-level transformer-less photovoltaic
(PV) inverter. In this topology, a 240V AC system is developed from a full bridge inverter circuit
using PIC microcontroller (PIC16F628A-I/P) connected to an array of PV panel through a power
factor correction circuit. The output waveform of theinverter depends on the type of pulse driver.
The inverter is connected to the utility supply, on the clear day, the ac load is served by
the inverter but on the cloudy day or night where solar irradiance is low, the inverterthrough its
PIC microcontroller automatically changes from the usage of inverter to the utility supply.
Objective of this paper is to optimize the maximum voltage angle to obtain the lowest current
total harmonic distortion (CTHD) of the uninterruptible power supply (UPS) on the three-level
single phase transformer-less inverter. In this paper, the maximum voltage angle optimization of
the AC three-level waveform transformer-less PV inverteris developed and created by a
microcontroller PIC16F627A-I/P changing maximum voltage angle of the AC three-level
waveform from 20° to 180°. Resistive load of 30 W lamp and inductive load of 20 W water
pump are applied to the transformer-less PV single phase inverter. The result shows that the
lowest CTHD of 15.448% is obtained when the maximum voltage angle is 134°.

shoot-through state which is prohibited in the conventional voltage-source inverter to avoid short
circuit, the proposed inverter can perform DC-DC boost conversion and DC-AC inversion
simultaneously based on the single-stage structure. Multiple inverter modules can be flexibly
configured in terms of terminal interconnections, and thus they can adapt to multiple energy
sources at different voltage levels and power capacities. More importantly, a shared DC bus
decouples the AC outputs of the interconnected inverter modules from their inputs and enables
the system to supply balanced power to the grid. Circuit modularization and minimum required
devices predict a significantly reduced cost; furthermore, the shoot-through operation offers a
great EMI immunity and reliability.

source inverters employ the Z-source/quasi-Z-source network and only two active switches to
achieve the same output voltage as the traditional voltage-fed full-bridge inverter does. The two
active switches of the semi-Z-source inverter are controlled complementarily. Different from the
traditional single-phase Z-source/quasi-Z-source inverter, shoot-through zero state is not
applicable to the semi-Z-source inverter. The input dc source and the output ac voltage of the
semi-Z-sourceinverter share the same ground, thus leading to less leakage ground current
advantages over other nondoubly grounded inverters, such as voltage-fed full-bridge inverter.
This is a preferred feature for nonisolated grid-connected inverters, especially in PV application.
A revised nonlinear sinusoid pulse width modulation method for a semi-Z-source inverter is also
proposed. By using this method, desired duty cycle can be generated to output the sinusoidal
voltage. Other dc-dc converters with similar voltage gain curve, which can also be used as a
single-phase inverter,   are   also   discussed   and   summarized.    A   single-phase    semi-Z-
source inverter prototype is built; experimental results are provided to verify and demonstrate the
special features of the proposed circuit.

                                      CAPABILITY
ABSTRACT :


       Solar integrated current-fed quasi-Z-source inverter (qZSI) have been proposed to
overcome the limitations of current-source inverter (CSI) and current-fed Z (impedance)
sourceinverter (ZSI). The problems with CSI are unidirectional power flow and can perform only
voltage boost operation. On the other hand ZSI is bidirectional with an additional diode and have
voltage buck-boost capability. The techniques of ZSI and qZSI are more or less the same but
qZSIs are considered to be more efficient and reliable. The drawback of ZSI is that the inductors
must sustain high currents. Space vector pulse-width modulation is analyzed in this paper; here
the power buck-boost capability is attained by changing the values of input inductance.
Simulation results are shown.

       DIODE CLAMPED THREE LEVEL INVERTER USING
                                  SINUSOIDAL PWM
ABSTRACT :


       An inverter is a circuit which converts dc power into ac power at desired output voltage
and frequency. The a.c. output voltage can be fixed at a fixed or variable frequency. This
conversion can be achieved by controlled turn ON & turn OFF or by forced commutated
thyristors depending on applications. The output voltage waveform of a practical inverter is non
sinusoidal but for high power applications low distorted sinusoidal waveforms are required. The
filtering of harmonics is not feasible when the output voltage frequency varies over a wide range.
There is need for alternatives. Three level Neutral Point Clamped inverter is a step towards it.

3) it does not require a front-end dc/dc converter; and 4) the topology has inherent voltage
boost/gain property thereby reducing the reliance on the transformer turns ratio.
The inverterrequires a smaller high-frequency transformer because a) the inverter switches at
100-kHz, b) the transformer voltage and current are bipolar in every switching cycle, and c) only
half the input current flows through the transformer at any given instant of time. To maintain the
THD within the acceptable limit, a harmonic compensation control using a proportional-resonant

voltage amplitude is not limited to DC voltage source and transformers turns ratios similar to
traditional cascaded transformer based multilevelinverter and can be increased with Z network
shoot-through state control. Besides, it is more reliable against short circuit. In this paper, by
using particular switching algorithm, the modulation index of inverter is kept constant and output
voltage is controlled by a shoot-through duty ratio, therefore Total Harmonic Distortion (THD)
of output voltage is nearly constant for different boost ratio. The performance of
suggested inverter and switching algorithm are validated with simulation results using
MATLAB/SIMULINK software.

gate driver circuits and capacitors, and blocking voltage on switches. The analytical analyses of
the power losses of the proposedconverter are also presented. The operation and performance of
the proposed multilevel converter have been evaluated with the experimental results of a single-

                 SCHEME FOR COMBINED MULTIPORT
                               DC/DC CONVERTERS
ABSTRACT :


       Multiport dc/dc converters are widely employed in hybrid energy generation systems to
provide stable power to key loads with high power density. In this paper, the switch duty cycle
and the phase angle of the interleaved converters are employed as two control freedoms to
achieve decoupled voltage regulation within a certain operating range among different ports,
which is referred to as pulsewidth modulation plus phase angle shift (PPAS) control scheme. An
interleaved bidirectional buck-boost converter and a full-bridge converter are integrated together
to derive a combined three-port dc/dc converter for photovoltaic (PV)-battery hybrid energy
systems, which is adopted as a typical example to explore the clear performance of the proposed
PPAS control strategy. The bidirectional buck-boost converterand the full-bridge converter share
the same power MOSFETs in the primary side, which simplifies the circuit structure and
improves the power density. The duty cycle of the interleaved bidirectional buck-
boost converter is adopted to realize the maximum power point tracking and the voltage balance
between the battery and the PV cell in the primary side. Furthermore, the phase angle of the
interleaved buck-boost converter is employed as another control freedom to achieve accurate

secondary output voltage regulation. Finally, a 100-W PV-Battery energy system is designed and
tested to verify the effectiveness of the proposed scheme.




 A LOW-POWER AC–DC SINGLE-STAGE CONVERTER WITH
               REDUCED DC BUS VOLTAGE VARIATION
ABSTRACT :


       A new low-power single-stage ac-dc converter is proposed in the paper. The outstanding
feature of the converter is that it can operate with a sinusoidal input current and a low primary-
side dc bus voltage that is much less variable than that found in other single-stage converters.
The operation of the converter is discussed in the paper and its various modes of operation are
explained in detail. An analysis of the converter's steady-state characteristics is performed and
the results are used in the design of the converter. Experimental results obtained from a
prototype converterare also presented.

   CONTROL OF IMPROVED FULL-BRIDGE THREE-LEVEL
  DC/DC CONVERTER FOR WIND TURBINES IN A DC GRID
ABSTRACT :


       This paper presents an improved full-bridge three-level (IFBTL) dc/dc converter for a
wind turbine in a dc grid by inserting a passive filter into the dc/dc converter to improve the
performance of the converter. The passive filter can effectively reduce the voltage stress of the
medium frequency transformer in the IFBTL dc/dc converter. A modulation strategy, including
two operation modes, is proposed for the IFBTL dc/dc converter. Then, a voltage balancing
control strategy is proposed for the IFBTL dc/dcconverter. Furthermore, the control of the wind
turbine based on the IFBTL dc/dc converter in a dc-grid system is presented. Finally, a small-

ac/dc power converter drives the electrical motor. Several tools may be needed to achieve an
optimal design of the inverter. This paper presents a simplified methodology to
estimate power losses in a two-level inverter made up with isolated gate bipolar transistors
(IGBTs). This methodology is based on the IGBT manufacturer datasheet; therefore, the
knowledge of internal parameters used in other more complex methodologies is not required.
The model is implemented inMatlab-Simulink and allows simulation of different powerdevices,
modulation techniques, and operating conditions very easily. Some results are obtained and
validated with commercial electronic software and also with the simulation tool Semisel,
provided by the manufacturer of the IGBTs.

ABSTRACT :


       This paper presents the design and application of a hub drive system for Hybrid (HEV)
and All Electric Vehicles (EV). Initially Matlab SIMULINK model of a hub driven hybrid
electric vehicle is developed and the performance values are calculated. Two 15 kW brushless dc
machines (BLDC) are designed and manufactured to be located inside the rim of the wheels. The
performance tests of these wheels are conducted in laboratory environment. Then, two separately
driven rear wheels are mounted to Fiat Linea vehicle. The mechanical differential is replaced by
an electronic control technique, which bases upon the detection of the angle of steering wheel. A
CAN bus communication is established between the control system of electric drive
and ElectronicControl Unit (ECU) of the vehicle. The concerted action between electrically
driven rear-wheels and Internal Combustion Engine (ICE) driven front axle is achieved. Finally
some preliminary road tests are executed and encouraging test results are obtained. The design
optimizations between ICE, Electric Drive and Battery Powerfor various drive cycles are
investigated.

    SIMULATION FOR SVPWM INVERTER-SMITH SINGLE-
                      PHASE MOTOR SPEED CONTROL
ABSTRACT :


       The transient performance of Smith single phase motor supplied by the single phase
SVPWM voltage source inverter is studied emphatically. And then, voltage space vector of the
single phase whole-bridge inverter is analyzed and the SVPWM whose control algorithm is
deduced. Meanwhile, a transient mathematical model for the Smith single phase motor is
developed. Moreover, a simulation model of variable frequency speed control system of single
phase SVPWM inverter-Smith single phase motor is built byMATLAB/SIMULINK. Finally, by
the simulation calculated to the actual case, the result is consistent with the theoretical analysis.
Thus, it would be of a certain practical significance and reference value in the design of SVPWM
inverter and speed control system of tri-winding single- phase condenser motor.

         A NOVEL WIND ENERGY CONVERSION SYSTEM
        WITH POWERQUALITY IMPROVEMENT FEATURES
ABSTRACT :


        This paper focuses on design and simulation of a novel small scale Wind Energy
Conversion    System     (WECS)      based    on   Permanent     Magnet     Generators       (PMGs)
and power electronicconverters. Electric power is generated using a PMG whose output is having
variable magnitude and variable frequency due to non-uniform wind velocity. In the proposed
system output of PMG is converted to constant DC using a full bridge rectifier and closed loop
boost converter. This constant DC output is converted to AC using Three Bridge Four Wire
(TBFW) interfacing inverter. One of the most common problems when connecting small
renewable energy systems to the electric grid concerns the interface unit between
thepower sources and the grid, as it can inject harmonic components that may deteriorate
the power quality. The TBFW inverter can perform as a conventional inverter as well as an
active power filter by means of hysteresis current controller. The inverter can thus be utilized as
a powerconverter injecting power generated from renewable energy source to the grid and as a
shunt   active power filter    to   compensate     for power quality   disturbances        and   load
reactive power demand.        Validation     of    the     proposed      system       is     verified
through MATLAB/Simulink simulation.

      A NEW MATRIX CONVERTER BASED THREE PHASE
                       BRUSHLESS DC MOTOR DRIVE
ABSTRACT :


       This paper presents a novel matrix converter based drive technique for three phase
brushless DC (BLDC) machines. Incontrast to existing matrix converter based drives, the
proposed technique uses a topology that has less number of semiconductors and a unique
switching sequence to drive three phase BLDC machines directly from single phase mains
supply lines without a DC link capacitor. The paper describesin detail both the topology and the
unique switching sequence that is essential for the proposed technique. A model based
on Matlab/Simulink is also presented to demonstrate the theoretical performance of the proposed
drive system. The performance of the technique is evaluated using a model of 320 W BLDC
machine, which is operated inboth torque and speed control modes, and simulated results
indicate that the performance of the machine is comparable to existing techniques. The proposed
technique is simple to implement, cost effective with low component count, and can be easily

         REAL-TIME LOAD COMPENSATION BY USING A
   CASCADED MULTILEVEL INVERTER-BASED STATCOM


ABSTRACT :


A delta-connected static synchronous compensator (STATCOM) is proposed for real-time load
compensation of unbalanced load. The structure of the STATCOM is a multilevel cascaded full
H-bridge inverter which is suitable for high-voltage, high-power applications. First, use of the
symmetrical components method derives the control algorithm of the STATCOM. The
STATCOM is then built in theMatlab/Simulink environment. Finally, simulation results indicate
that the proposed delta-connected STATCOM is effective for real-time load compensation of
unbalanced loads.

   MODELING AND CONTROL OF DIRECTLY CONNECTED

are connected to the main grid through a Point of Common Coupling which separates the former
from the latter. At the time of an intentional islanding or fault at the grid level, a microgrid is
able to disconnect itself from the rest of the grid and operate by itself. A microgrid may contain
both directly connected and inverter interfaced sources with different control configurations.
When disconnected or islanded from the main grid there are various approaches to share the
load, one of them being master-slave control where a storage device may become the reference
DG to set the nominal voltage and frequency. When the main grid is brought back to normal
operation, the microgrid is able to resynchronize itself to the main grid only when it meets
certain conditions so as to avoid transients. All the micro sources, power electronics and their
control with power management were developed in Matlab/Simulink.

          This paper describes the modeling and analysis of the dynamics of an electronic load
sensing hydraulic system consisting of a load sensing pump, a flow control valve, a hydraulic
cylinder and an effective mass representing the linkage inertia. Load sensing hydraulic circuits
are prone to instabilities and frequently require hydraulic filters in the form of orifices and
control volumes to remove unwanted oscillations. Closed loop controllers for such systems are
difficult to design due to the nonlinearities and high order transfer functions. In this paper a
linear model is derived from equations of motion, and validated against a nonlinear simulation
model based on MATLAB. Then, a third order model is derived that can be used for controller
design.

 A NEW BOOST TYPE CASCADED INVERTER WITH SINGLE
                                      DC SOURCE
ABSTRACT :

       Cascaded multilevel inverters with Y connection or Delta-connection have been proposed
for high voltage applications. However, these topologies always require isolated transformers for
each inverter cell, which makes cost high and wiring complex. Furthermore, system weight and
volume also increase accordingly. This paper presents two new types of boost type delta-
connection cascaded inverters with only a single DC source. Based on it, a suitable voltage
control with PWM modulation is also proposed to improve the inverter control performance and
DC capacitors voltage fluctuation. Verification has been carried out by simulation
with MATLAB.

Address: No.73, karuneegar street, Adambakkam, Chennai-88 ACTIVE POWER FILTER BASED ON CASCADED TRANSFORMER MULTILEVEL INVERTER ABSTRACT : The widespread increase of non-linear loads nowadays, significant amounts of harmonic currents are being injected into power systems. Harmonic currents flow through the power system impedance, causing voltage distortion at the harmonic currents’ frequencies. The distorted voltage waveform causes harmonic currents to be drawn by other loads connected at the point of common coupling (PCC). The use of grid connected power electronic converters to improve power quality in power distribution systems represents the best solution, in terms of performance and stability, for the elimination of harmonic distortion, power factor correction, balancing of loads, and voltage regulation. The traditional method of current harmonics reduction involves passive LC filters, which are its simplicity and low cost. However, passive filters have several drawbacks such as large size, tuning and risk of resonance problems In this project, we propose an APF based on cascaded H-bridge multilevel converter which employs one single dc input power source and isolated single-phase low-frequency transformers. By the proposed circuit configuration, a number of dc-link can be reduced, compared with traditional APF based on cascaded H-bridge multilevel converter. With this type of topology, higher voltage levels can be achieved, making the proposed topology suitable for compensation of medium and high voltage power distribution systems. A simple control scheme is used for the correct operation of inverter and compensation demands. The current reference required can be obtained allowing the generation of the total compensating current and the absorption of the needed active power to compensate converter losses and to keep the dc voltages constant.

Simulation results show the validity and effectiveness of presented active power filter for compensation of harmonic currents, reactive power and unbalance currents. A PRACTICAL TECHNIQUE FOR POWER QUALITY IMPROVEMENT FOR SINGLE PHASE INDUCTION MACHINES ABSTRACT : Most of the electrical loads in our daily life are single phase as well as inductive. Single phase induction machines are one of the many reasons for poor quality power supply along with some concerns on torque requirements, accelerating time, starting current, and dip in voltage and harmonics in input current. During starting, power supply is more adversely affected. When single motors at homes are started, a visible fluctuation in lights is observed. This is due to the poor quality of power during starting of single phase induction motor. When the motor is started, it draws high starting current. This high current cause’s dip in the voltage during starting intervals, because there is a lot of voltage drop across the distribution conductor. This project presents an analysis of all the above mentioned problems along with a practical way to mitigate them. In this project, induction motor under test is the capacitor run motor. In this project a practical approach is presented using classical LC circuit techniques. The results and tests performed before and after application of the proposed solution have been analyzed and presented. The frequency, running current waveform current components in time domain are simulated using MATLAB/Simulink software, The conclusions presented in this

A COMPARISON OF SYMMETRICAL AND ASYMMETRICAL THREE-PHASE H-BRIDGE MULTILEVEL INVERTER FOR DTC INDUCTION MOTOR DRIVES ABSTRACT : Multilevel voltage-source inverters are intensively studied for high-power applications and standard drives for medium-voltage industrial applications have become available Solutions with a higher number of output voltage levels have the capability to synthesize waveforms with a better harmonic spectrum and to limit the motor winding insulation stress. Earlier studies have
  • 5. IEEE 2012 MATLAB Titles & Abstract FOR REGISTER: www.finalyearstudentsproject.com CONTACT NO.: 91-9176696486. Address: No.73, karuneegar street, Adambakkam, Chennai-88 pointed out the limitations of conventional inverters, especially in high-voltage and high-power applications. In recent years, multilevel inverters are becoming increasingly popular for high-power applications due to their improved harmonic profile and increased power ratings. Several studies have been reported in the literature on multilevel inverters topologies, control techniques, and applications. However, there are few studies that actually discuss or evaluate the performance of induction motor drives associated with three-phase multilevel inverter. This project presents then a comparison study for a cascaded H-bridge multilevel direct torque control (DTC) induction motor drive. In this case, symmetrical and asymmetrical arrangements of five- and seven-level H-bridge inverters are compared in order to find an optimum arrangement with lower switching losses and optimized output voltage quality. For the validation of the earlier discussed control approach, simulations and experiments have been carried out. The carried out experiments show that an asymmetrical configuration provides nearly sinusoidal voltages with very low distortion, using less switching devices. Moreover, torque ripples are greatly reduced. Simulation results for five levels cascaded and seven-level H-bridge inverter Shown using MATLAB/Simulink software.

Voltage sag is the most power quality problem facing now days in distribution system; this project discusses the control and performance of a low-voltage DVR using a high-frequency isolated dc–dc converter. The high- frequency (20-kHz) transformer in the dc–dc converter is much smaller, for example, one- hundredth, in volume than the line-frequency transformer. DVR, which is characterized by connecting the shunt converter (the diode rectifier) to the supply side. The DVR consists of shunt and series converters connected back to back and a common dc capacitor as an energy-storage device. Multilevel topologies such as diode-clamped or cascaded pulse width modulation (PWM) converters can eliminate line frequency transformers from medium-voltage applications, A main motivation of the isolated dc–dc converters is to replace line-frequency transformers with high-frequency transformers, in which galvanic isolation is indispensable between the two sets of dc terminals; Experimental results obtained by a 200-V 5-kW laboratory system have verified the viability and effectiveness of the DVR. In the near future, replacing Si devices with SiC devices will bring significant reductions in volume and weight to the dc–dc converter, as well as the series converter. Simulation has been done using MATLAB/SIMULINK software.

Recently more renewable power conversion systems are connected in low voltage ac distribution systems as distributed generators or ac micro grids due to environmental issues caused by conventional fossil fueled power plants. Recently dc grids are resurging due to the development and deployment of renewable dc power sources and their inherent advantage for dc loads in commercial, industrial and residential applications, the dc micro grid has been proposed to integrate various distributed generators. However, ac sources have to be converted into dc before connected to a dc grid and dc/ac inverters are required for conventional ac loads. This project proposes a hybrid ac/dc micro grid to reduce the processes of multiple dc– ac–dc or ac–dc–ac conversions in an individual ac or dc grid. The hybrid grid consists of both ac and dc networks connected together by multi-bidirectional converters. AC sources and loads are connected to the ac network whereas dc sources and loads are tied to the dc network. Energy storage systems can be connected to dc or ac links. The proposed hybrid grid can operate in a grid-tied or autonomous mode. The coordination control algorithms are proposed for smooth

A MODIFIED C-DUMP CONVERTER FOR BLDC MACHINE USED IN A FLYWHEEL ENERGY STORAGE SYSTEM ABSTRACT : The permanent magnet brushless DC machine (BLDCM) is one of the suitable motors for the flywheel energy storage system (FESS) The common half-bridge topology for high-speed BLDCM. It includes a buck chopper and a half-bridge converter. Compared with the full-bridge converter, the half bridge converter has half the number of switches and avoids the short circuit across the phase leg in the full-bridge converter. However, this half-bridge topology has two disadvantages for the FESS: 1) the energy unidirectional flow, and 2) the energy of the turnoff phase is consumed on the resistance which means the waste of energy.

A MINIMUM POWER-PROCESSING-STAGE FUEL-CELL ENERGY SYSTEM BASED ON A BOOST-INVERTER WITH A BIDIRECTIONAL BACKUP BATTERY STORAGE ABSTRACT : When low-voltage unregulated fuel-cell (FC) output is conditioned to generate ac power, two stages are required: a boost stage and an inversion one. A two-stage FC power conditioning system to deliver ac power has been commonly considered and studied. The system usually includes transformer-type dc–dc boost converter stage and dc-to-ac inverter stage with auxiliary energy unit. This type of power conditioning system has inevitable drawbacks, such as being bulky, costly, and inefficient, because each stage has to have a high efficiency for higher overall efficiency and normally more than six active components (switches and diodes) are required. In order to minimize the problems with a two-stage FC power conditioning system, a topology with reduced power processing and conversion stages is required. A topology that is

The double-loop control scheme of this topology has also been proposed for better performance, even during transient conditions. In this paper, the boost-inverter topology that achieves both boosting and inversion functions in a single stage is used to develop an FC-based energy system that offers high conversion efficiency, low-cost, and compactness. The proposed system incorporates additional battery-based energy storage and a dc–dc bidirectional converter to support instantaneous load changes. The output voltage of the boost-inverter is voltage-mode controlled and the dc–dc bidirectional converter is current-mode controlled. The load low-frequency current ripple is supplied by the battery, which minimizes the effects of such ripple being drawn directly from the FC itself. Analysis, simulation, and experimental results are presented to confirm the operational performance of the proposed system.

The main purpose is to detect and compensate for the voltage sag with minimum DVR active power injection. Also, the in-phase compensation method can be used for sag and swell mitigation. The multiline DVR can be used for eliminating the battery in the DVR structure and controlling more than one line. Moreover, research has been made on using the DVR in medium level voltage. Harmonic mitigation and control of DVR under frequency variations are also in the area of research. The closed-loop control with load voltage and current feedback is introduced as a simple method to control the DVR. The proposed algorithm is applied to some disturbances in load voltage caused by induction motors starting, and a three-phase short circuit fault. Also, the capability of the proposed DVR has been tested to limit the downstream fault current. The current limitation will restore the point of common coupling (PCC) (the bus to which all feeders under study are connected) voltage and protect the DVR itself. The innovation here is that the DVR acts as a virtual impedance with the main aim of protecting the PCC voltage during downstream fault without any problem in real power injection into the DVR. The basis of the proposed control strategy in this project is that when the fault current does not pass through the DVR, an outer feedback loop of the load voltage with an inner feedback loop of the filter capacitor current will be used. Also, a feed forward loop will be used to improve the dynamic response of the load voltage. Moreover, to improve the transient response, the Posicast controller and to eliminate the steady-state error. Simulation results show the capability of the DVR. A NEW METHOD FOR POWER QUALITY IMPROVEMENT IN CLASSICAL AC/AC VOLTAGE CONTROLLERS USING PWM TECHNIQUE ABSTRACT :

Address: No.73, karuneegar street, Adambakkam, Chennai-88 There are three basic types of AC to AC converters. The simplest ones, the AC voltage controllers, allow controlling the output voltage only, while the output frequency is the same as the input frequency. The second one is the Cycloconverters. In Cycloconverters, the output frequency can be controlled, but it is at least one order of magnitude lower than the input frequency. In both the AC voltage controllers and Cycloconverters, the maximum available output voltage approaches the input voltage. The last one is the matrix converter. Because of having no inherent limits on the output frequency, matrix converters are most versatile, but the maximum available output voltage is about 15% lower than the input voltage AC voltage controllers are widely used to obtain variable AC voltage from fixed AC source. A lot of topologies of pulse-width modulated (PWM)-AC voltage controllers for single- phase and three phase systems are proposed up to date. PWM-AC controllers have important advantages compared with the phase-controlled AC voltage controllers using Thyristors and Triacs. This project presents a novel control technique for application to PWM-AC controllers with ability of generating smaller harmonics. In the proposed control method, both the traditional AC voltage controllers and the PWMAC controllers are combined, smaller THD values are obtained and switching losses are minimized. Thus, the harmonic pollution in the power system will be reduced and the power quality will be increased. In order to investigate the proposed controller performance, computer simulations are performed. Obtained results are compared with those of the conventional PWM-AC controller According to the simulation sector-control with PWM method has better performance than phase-angle control with PWM method does. So, sector-control with PWM method is recommended to the power community. This method can be of practical value in replacing the conventional counterparts that are used in controlling heating elements and speed control of small fractional horsepower induction motors. Simulation results are conducted using MATLAB/SIMULINK software.

Using multilevel technique, the amplitude of the voltage is increased, stress in the switching devices is reduced and the overall harmonics profile is improved. Among the familiar topologies, the most popular one is cascaded multilevel inverter. It exhibits several attractive features such as simple circuit layout, less components counts, modular in structure and avoid unbalance capacitor voltage problem. However as the number of output level increases, the circuit becomes bulky due to the increase in the number of power devices, the general purpose of the multilevel inverter is to synthesize a nearly sinusoidal voltage from several levels of dc voltages, typically obtained from capacitor voltage sources. As the number of level increases, the synthesized output waveform has more steps, which produce a staircase wave that approaches a desired waveform. Also as more steps added to the waveform, the harmonic distortion of the output waveform decreases, approaching zero as the level increases. As the number of level increases, the voltage that can be summing multiple voltage levels also increases. These new types of converters are suitable for high voltage and high power application due to their ability to synthesize waveforms with better harmonic spectrum. Numerous topologies have been introduced and widely studied for utility and drive applications. Amongst these topologies, the multilevel cascaded inverter was introduced in Static VAR compensation and drive systems. This project presents a new technique for getting a multilevel output and also uses PWM control techniques. In this technique, the number of switches used for the dc to ac conversion is reduced. So this dc to ac conversion significantly reduces the initial cost. This technique exhibits some attractive features which suits industrial applications. MATLAB/Simulink environment is used to simulate the results.

A NOVEL APPROACH IN SOFT STARTING OF LARGE INDUCTION MOTORS ABSTRACT : The electric power consumption of AC motor is a great part of the total domestic consumption. So, high efficiency and stability of AC motor can realize energy-saving and cost reducing effectively. Not only AC motor need to be soft-started to lessen current surge and electric fence voltage-drop, but also its speed need to be able to adjusted to improve efficiency. If the induction motor is started directly, its starting current will be up to 5-8 times the rated value, which causes a sharp decline in voltage of the connecting power network, affecting normal operation of other equipments and causing a great impact on the motor, especially on cage-type rotor whose bars and rings would be destroyed enormously. As the development of the power electronics technology, computer control technology and automatic control technology, electronic soft-start controller has appeared, while in generally, the starters on the market only have basic modes such as current-limited and voltage step ramping soft-start. Although it can meet the demands of most kinds of loads, the start state is not optimal, direct online induction machine starts have many disadvantages. Torque pulsations are often large and vary from positive to negative values. These torque transients in a motor shaft are transmitted to the load, resulting in mechanical wear in the motor bearings and load couplings. Therefore, properly controlling the starting currents and torques of induction machines is of great importance in many instances. This project proposes a new series compensator based circuit for soft starting of IM. This circuit consists of a diode-bridge type DC reactor that connects in series with each phase of transformer. It does not need any control, measurement and gate driving circuits. The power circuit simplicity, reliable operation and almost no effect on normal operation of IM are other advantages of proposed circuit.

A NOVEL BVC-RBF NEURAL NETWORK BASED SYSTEM SIMULATION MODEL FOR SWITCHED RELUCTANCE MOTOR ABSTRACT : THE switched reluctance motor (SRM) drive is considered as an attractive candidate for variable speed motor drives due to its low cost and rugged structure, reliable converter topology, and high efficiency over a wide speed range, and fault-tolerant performance. These drives are suitable for applications such as electric vehicles, aircraft starter/generator systems, mining drives, robotics, and. On the one hand, several approaches have been reported in the literature for obtaining and describing the flux linkage characteristics of SRM, FEA is the most commonly used method for calculating the flux linkage characteristics without experimental measurement, which is quite suitable for machine design and performance prediction. Nevertheless, almost all of the aforementioned intelligent approximation methods such as ANN, ANFIS, and RBF are conditioned on that the model is determined based on the observational data only.

The purpose of this project is to develop a SRM system simulation model considering the critical problems as discussed above. In this projetc, a double scalar magnetic potential method (DSMP) based 3-D FEM together with enhanced incremental energy method (EIEM) is used for flux linkage calculation, which considers the end effect and reduces the computation time.

A SEVEN-LEVEL INVERTER TOPOLOGY FOR INDUCTION MOTOR DRIVE USING TWO-LEVEL INVERTERS AND FLOATING CAPACITOR FED H-BRIDGES ABSTRACT : THE capability of multilevel inverters to generate voltage waveform with less harmonic distortion, at reduced switching frequency, using switching devices of low-voltage ratings makes them preferred choice for medium- and high voltage power processing applications. This has led to their increasing applications in the control of medium and high voltage ac drives .Though with increase in number of levels the quality of waveform improves, it also increases the complexity of the circuit due to the increase in the number of devices and associated control circuitry. The other issues of concern in industrial applications are reliability and efficiency of the system. Hence, the researchers in this field are focused mainly on the development of less complex, more reliable and efficient multilevel inverter topologies. A survey of multilevel inverter topologies is presented. The conventional multilevel converters include the neutral point clamped (NPC), flying capacitor, and cascaded H-bridge topologies. Dual inverter configuration for an open-end winding induction motor is another interesting multilevel topology for drive applications.

Address: No.73, karuneegar street, Adambakkam, Chennai-88 The seven-level inverter topology proposed in this is intended for an induction motor with open-end winding structure. Here, in addition to two two-level inverters feeding the coils from both ends, two H-bridge cells are connected in series with the motor winding in each phase. These H-bridge cells are fed by capacitors whose voltages are maintained at the required level. An important advantage of this topology is the reduction in dc-link voltage requirement by half when compared with the requirement of dc-link voltage in NPC topology. In this topology, there are multiple ways of generating middle voltage levels and this feature is utilized in balancing the capacitor voltages in the entire modulation range. It needs only two isolated dc-voltage sources of voltage rating Vdc /2 where Vdc is the dc voltage magnitude required by the conventional neutral point clamped (NPC) seven-level topology. The proposed topology is capable of maintaining the H-bridge capacitor voltages at the required level of Vdc /6 under all operating conditions, covering the entire linear modulation and over modulation regions, by making use of the switching state redundancies. In the event of any switch failure in H-bridges, this inverter can operate in three-level mode, a feature that enhances the reliability of the drive system. The two level inverters, which operate at a higher voltage level of Vdc /2, switch less compared to the H-bridges, which operate at a lower voltage level of Vdc /6, resulting in switching loss reduction. The experimental verification of the proposed topology is carried out for the entire modulation range, under steady state as well as transient conditions. Simulation results are studied using MATLAB/SIMULINK software.

In the paper, we will discuss about the cascaded multilevelinverter. The cascaded multilevel inverter uses series strings of single phase full bridge inverter to construct multilevel phase legs. A particular advantage of this topology is that the modulation, control and protection requirement of each bridge are modular. Moreover, multilevel inverter topologies are able to generate better output quality, while operating at lower switching frequency. This implies lower switching dissipation and higher efficiency. In this paper, the conventional PWM inverter and the cascaded multilevel PWMinverter is modeled in MATLAB Simulink. The analysis of the conventional PWM inverter and the cascaded multilevel PWMinverter using unipolar and bipolar switching schemes is done and finally the results are compared.

The two active switches of the semi-Z-source inverter are controlled complementarily. Different from the traditional single-phase Z-source/quasi-Z-source inverter, shoot-through zero state is not applicable to the semi-Z-source inverter. The input dc source and the output ac voltage of the semi-Z-sourceinverter share the same ground, thus leading to less leakage ground current advantages over other nondoubly grounded inverters, such as voltage-fed full-bridge inverter. This is a preferred feature for nonisolated grid-connected inverters, especially in PV application.

Other dc-dc converters with similar voltage gain curve, which can also be used as a single-phase inverter, are also discussed and summarized. A single-phase semi-Z- source inverter prototype is built; experimental results are provided to verify and demonstrate the special features of the proposed circuit.

To maintain the THD within the acceptable limit, a harmonic compensation control using a proportional-resonant (PR) controller is implemented. Analysis, design, and simulation results of the proposedinverter are presented. Soft-Switching Analysis Of A Resonant Capacitor Current Feedback Self-Oscillating Inverter ABSTRACT :

In this paper, the switch duty cycle and the phase angle of the interleaved converters are employed as two control freedoms to achieve decoupled voltage regulation within a certain operating range among different ports, which is referred to as pulsewidth modulation plus phase angle shift (PPAS) control scheme. An interleaved bidirectional buck-boost converter and a full-bridge converter are integrated together to derive a combined three-port dc/dc converter for photovoltaic (PV)-battery hybrid energy systems, which is adopted as a typical example to explore the clear performance of the proposed PPAS control strategy. The bidirectional buck-boost converterand the full-bridge converter share the same power MOSFETs in the primary side, which simplifies the circuit structure and improves the power density. The duty cycle of the interleaved bidirectional buck- boost converter is adopted to realize the maximum power point tracking and the voltage balance between the battery and the PV cell in the primary side.

Electric power is generated using a PMG whose output is having variable magnitude and variable frequency due to non-uniform wind velocity. In the proposed system output of PMG is converted to constant DC using a full bridge rectifier and closed loop boost converter. This constant DC output is converted to AC using Three Bridge Four Wire (TBFW) interfacing inverter. One of the most common problems when connecting small renewable energy systems to the electric grid concerns the interface unit between thepower sources and the grid, as it can inject harmonic components that may deteriorate the power quality. The TBFW inverter can perform as a conventional inverter as well as an active power filter by means of hysteresis current controller. The inverter can thus be utilized as a powerconverter injecting power generated from renewable energy source to the grid and as a shunt active power filter to compensate for power quality disturbances and load reactive power demand. Validation of the proposed system is verified through MATLAB/Simulink simulation.
