Introduction to Comprehensive Power
 Comprehensive Power is a leading
designer and manufacturer of high-
performance permanent magnet (PM)
motors, generators, controls and drives
 We provide enabling technology for
rugged industry applications including
global oilfield, military, marine propulsion
and renewable energy, as well as
machines which require high torque
 We were founded in 1998, and are
located in Marlborough, MA
 We Invent and Produce Unique Solutions
which are Manufactured in the USA

Why PM motors?
 Full torque, even at stall speed.
 Motors can operate with higher speeds and
greater precision than achieved by the
established fluid or electromechanical
drive technologies.
 Direct-drive torque motor modules reduce
the need for power transmission
components such as gear boxes, couplings
and linkages, thereby reducing the
efficiency losses in machinery created by
these components.
 Global market for direct drive torque
motor modules has grown from $98
million in 2008 to $195 million in 2012 and
is forecast to grow to be worth nearly
$300 million in 2016.

12. The Most Advanced Modular Drive System
The image on the right
features multiple racks of
TIM-270s, or TIMs
(TeraTorq® Inverter
Modules).
Page 12Comprehensive Power Proprietary

13. TIMs
 200kW / 250Hp power, 9”x9”x25” modules,
typically deployed in arrays
 TIM-270 modules are fully interchangeable with
each other, reducing the number of spare parts
needed to be stocked. Any TIM automatically
performs:
 AC/DC Rectification
 DC/AC Inversion
 DC/DC Power Balancing
 TIMs are used to:
 Drive motors
 Transfer power from a generator or other
source
 Transfer power to/from a switchboard or a
battery bank
Page 13Comprehensive Power Proprietary

14. Theory of Operation - TIMs
 Each module has 6 power terminals
 DC plus, minus and ground
 3 AC (input / output) phases
 Connected to DC by IGBT switches
 Current can flow in any direction based on switch control
 IGBTs switch rapidly with Pulse Width Modulation (PWM) control
 Output is smoothed by phase inductors
 Harmonics are actively controlled and reduced
 AC voltage is between DC plus and minus
 AC phases provide or draw current on command, at any
frequency from DC to 1,000 Hz
 Modules automatically balance loads when connected in parallel
 Can draw power from lower AC voltages with active power factor
correction

15. TIMs
 Designed for continuous “always on” redundant, fail-
safe system operation
 The unlikely event of a failure of a TIM-270 in a
multiple TIM system only decreases the system power
proportionately
 Such a failure will still yield continued system operation
and avoid emergency equipment shutdown
 TIM-270 modules can safely and easily be swapped or
replaced by anyone; no factory certification or special
training is required. Replacing a TIM-270 is a simple
“plug and play” operation.
Page 15Comprehensive Power Proprietary

16. TFMs (TeraTorq® Frame Modules)
 Modular, expandable drive mounting system
 Power
 Liquid cooling
 Control
 TFMs hold up to 4 TIMs
 About 49” tall, 30.5” deep, 10” wide
 All module connections are blind mate quick
disconnect for safe and foolproof operation
Page 16Comprehensive Power Proprietary

17. TCM (TeraTorq® Control Module)
 Controls the operation of TIM lineups, which may
be connected to motors, generators, renewable
energy sources, batteries, ultracaps, switchboards,
etc
 Provides information to/from a system controller
via the Modbus Application Protocol (MBAP) over an
Ethernet TCP/IP connection
 Support for web based data collection,
troubleshooting, and preventative maintenance
programs
 System status is continuously logged locally and can be viewed
over the internet
 Mode, power, status information
 Voltages, speeds , currents, temperatures
 Battery health (in hybrid systems)
 Fault reporting and identification
 Remote support personnel can spot many problems before they
interfere with operation
 Can help work through any unusual situation

26. FAQs
 Can I use TIM drive lineups with motors or generators
that are not manufactured by Comprehensive Power?
 Yes you can (although we would like you to consider all
of our equipment, including our motors and generators,
our drives are compatible with products from other
manufacturers).
 Can a TIM really be replaced by non-factory personnel?
 Yes. After following your defined safe procedure to open
the circuit breaker for the drive line, just push a button
and pull the handle to remove a TIM, and then slide a
replacement in.
 Can I use my own housing for my TIMs, TFMs, and TCMs?
 Yes. we will assist your design efforts and support the
deployment of the equipment within your own housing.
 Also we sell rack systems and cabinets, and we can also
recommend partners who also sell racks and cabinets for
our power electronics.
Page 26Comprehensive Power Proprietary

27. FAQs (con’d)
 If a TIM fails, does my system stop operating?
 No. In the unlikely event of a TIM failure, the
remaining TIMs will continue to operate, and the drive
lineup will have proportional power available.
 Does a TIM need to be programmed or require a hardware
modification to perform an AC/DC conversion or another
function?
 No. Any TIM can perform any function, and any TIM
can be placed in any TFM slot. The TIM’s function is
controlled by a TCM which is part of the drive lineup.
 Can this drive and power electronics system function as a
Microgrid?
 Yes. TIM systems support power being supplied from
one or multiple sources, including transformers,
switchboards, grid connections, generators and battery
banks. Power can be distributed to multiple loads,
including hotel loads, MCCs, motors and battery banks.
