Integrated Traction System – SPIRC-01 Locomotive India
The SPIRC-01 is a high power traction drive for locomotives,
2.5MW per drive. The SPIRC-01 cubicle is built around the water
cooled IGBT power module 3W45-600, resulting in a very high
power to volume ratio.
The SPIRC-01 consists of three converters:
•
2 line converters to convert AC input to a stable DC-link
voltage;
•
3x inverter to converts DC-link voltage to 3 phase AC for 3
850kW traction motors, independent motor control;
•
1x soft-crow bar down chopper to control and protect the
DC-link against overvoltage’s.
2x line inverter 1x soft crow bar 3x inverter
Summary.
The three converters inside the SPIRC-01 are all using the same
power module; a configuration connector makes the module
function specific. One power module consists of 2 phase legs.
The SPIRC-01 cubicle comprises of 9 power modules (18 phaselegs).
All Strukton traction systems are short-circuit proof and provide protection against over current, overvoltage, earth fault
and over temperature.
Strukton offers a complete range of traction systems with such standard IGBT power modules.

Design philosophy IGBT power module
The core of the chopper consists of two IGBT power
modules. A power module generally contains 2 pairs
of IGBT’s (2 Top & 2 Bottom IGBT’s), and is fitted
with control and protection logic, current transducers
and cooling arrangement.
