Use
of Latest Generation IGBT Specifically Designed
for Traction Application
|
| |
The novelty
of the development is the use of latest
generation IGBT specifically designed for the
traction
application with the high speed Digital Signal
Processor for the
fast response and smooth control of the dc
motors. Amtech's
application of IGBT power semiconductors to DC
traction motors
delivers greatly improved reliability,
performance, and efficient
use of electric energy to the Mass Transit
Industry using,
or wishing to investigate, the new DC
traction-control
technology. The new IGBT Based PWM DC Drives are
installed in new vehicles and are easily fitted
to older vehicles.

High-Speed
32-bit Digital Signal Processor
|
| |
The use of
high-speed 32-bit digital signal processor
provides tight control of the output current
and so protects the motor from overloading. This
helps to reduce the wear & tear and
maintenance cost.
