Comprehensive Power's TIM provides a uniquely modular and resilient "always on" VFD lineup for manufacturing floors and test stands. Each module can drive up to 250Hp and can be networked to control up to 16,000Hp motors. The same module can also be used for DC/AC conversions and DC/DC power management as well.

The Most Advanced Modular VFD System
for Manufacturers

2. Introduction to Comprehensive Power
 Comprehensive Power is a leading
designer and manufacturer of high-
performance permanent magnet motors,
generators, controls and drives.
 Founded in 1998, located in 40,000
square feet across 3 facilities in
Marlborough, MA
 We Invent and Produce Unique Solutions
which are manufactured in the USA

3. TIMs (TeraTorq® Inverter Modules)
 200 kW / 250 Hp power conversion and control “building
blocks”, often deployed in arrays
 TIM-270 modules are fully interchangeable with each other,
reducing the number of spare parts you need to stock. Any
TIM can be perform:
 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

4. 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

5. IGBT Phase to Phase Voltage
 Conventional
drives connect this
voltage directly to
the motor
terminals
 Fast transients
result in
 Extra stress on
motor insulation
 Electromagnetic
Interference
 Increased heat
loss in rotor and
stator

6. Motor Terminal Voltage with TIMs
 Phase inductors in
each TIM locally
filter and contain
the high frequency
 Eliminates many of
the problems seen
with inverter
driven motors
 Eliminates the
need for special
cables and
shielding

features multiple racks
of TIM-270s, or TIMs
(TIMs are TeraTorq®
Inverter Modules).

8. TIMs
 Designed for durability and for continuous, “always
on”, fail-safe 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.

9. TFMs (TeraTorq® Frame Modules)
 TFMs hold up to 4 TIMs
 All module connections are blind mate quick
disconnect for safe and foolproof operation and
maintenance

10. TCM (TeraTorq® Control Module)
 Controls the operation of TIMs, which are
connected to motors, generators, 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

11. 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, you are not required to do so).
 Can a TIM really be replaced by non-factory personnel?
 Yes. Push the red button and pull the handle.
 Can I use my own housing for my TIMs, TFMs, and TCMs?
 Yes. We do sell rack systemd which house TFMs,
TCMs, and TIMs, but we will assist your design efforts
and support the deployment of the equipment within
your preferred housing.

12. FAQs (con’d)
 If a TIM fails, does my system need to be restarted?
 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 control system function as a Microgrid?
 Yes. TIM systems support power being supplied from
one or multiple sources, including transformers,
generators and battery banks. Power can be
distributed to multiple loads, including hotel loads,
MCCs, motors and battery banks.
