Project Description

Rail Traction Inverter Test System

The rail inverter test system uses a pulse test methodology to verify proper operation of the IGBT switching elements in a subway car motor control. The system is designed to verify proper commutation of the switching elements. A large capacitor bank allows testing at DC voltages up to 1kV and peak currents of up to 3kA into reactive loads.

The system also integrates self test capabilities and safe-to-turn-on (STTO) diagnostics to ensure no gross faults are present prior to the application of high voltages. Further the system includes dielectric withstand (hi-pot) test capability to ensure electrical safety.

A laminated safety enclosure surrounds the DUT to ensure operator protection. This guard is interlocked to prevent exposure to residual voltage stored in the DUT and system capacitor banks until automatically discharged.

Electromechanica is an established leader in the design of LabVIEW based automated test systems for a wide range of industries including rail, transportation, industrial controls, safety systems, manufacturing automation & test.
