DESIGN AND IMPLEMENTATION OF 600VA UPS based 0n 89C51
ABSTRACT
UPS control using micro controller is highly reliable less complex and economical
when compared the conventional UPS system. This paper explains about the design
and implementation of UPS using micro controller. The micro controller is mainly used
for control applications. So, micro controller is used for this proposed work. The main
function of the UPS (uninterrupted power supply) is to provide an uninterrupted power
supply and it should function automatically when the mains supply cutoff. This
automatic function in the conventional UPS is done by control system. It involves
certain complex work. So, in this proposed work, micro controller does the automation
of the UPS. Some of the automatic functions to be done by the micro controller are
overload protection, no load release, deep discharge cutoff and inverter operation.
There are different types of micro controller families. In this proposed work, the
micro controller-89S52 because of its high on chip ROM capacity, RAM capacity, serial
ports, input ports, etc. The micro controller 89S52 is superior in its memory capacity.
This micro controller is best suited for fast development. Since flash memory can be
erased in few seconds compared to the twenty minutes or more needed for the 8751.
By this, 89S51 is used to eliminate the waiting time needed to erase the chip and
thereby speedup the development time. It is a 40 pin micro controller in which 3 pins
are used for serial interfacing, i.e., one acts as receiver another acts a transmitter and
the third as ground. By this we can interface any components serially, it has 4 ports,
port 0, port 1,port 2 and port 3 and it is used for various functions of UPS such as on

load release, deep discharge cutoff and so on. This micro controller can be operated at
high frequencies and it consumes low power. Thus it is ideal for many projects.
There are different types of UPS. They are OFF line UPS and ON line UPS. This
paper focuses on the design of Offline UPS. Because it is mostly prepared than ON line
UPS. For example, it finds its application in the household appliances, a personal
computer, and so on.
The transistors used in UPS design are replaced, as MOSFET’S because of its
certain special features as positive temperature coefficient so that it has high current
carrying capability. It has low switching losses and the MOSFET turn on and turn off
can be obtained rapidly. Also it is easily available and has switching performance.
The conventional UPS system involves complex control system. In order to
reduce the complexity of the control system of conventional UPS embedded controller
are currently being used. This project describes the design and implementation of
1KVA.
