Propulsion inverters (VVVF Inverter)｜Transportation

Propulsion inverters (VVVF* inverters) are the control devices that convert the train''s power source to a suitable type of power to drive the traction motors. These inverters convert incoming DC power to AC power as well as control the amount of power (voltage and frequency) being supplied in accordance with the train''s speed, etc.

The Research For IGBT Replacement Of Auxiliary Inverter

So do the power electronic devices on the inverters. Insulated Gate Bipolar Transistor (IGBT) has taken place of the early device such as thyristor, power thyristor and Gate Turn-Off thyristor (GTO).There had been a high failure rate on AC01/02 train auxiliary inverter system since the trains came into the commercial service in 1999.

TCMS

[Objective] In the current mainstream of train auxiliary power supply systems, such as cross-supply method and extended supply method, the failure of a single SIV (auxiliary inverter) can impact the normal operation of electrical equipment on the train.

Take a metro train with two groups as an example, each group has three cars. If the centralized power supply mode is adopted, all the power of each group is concentrated on one auxiliary inverter (240kVA), and only two auxiliary inverters are needed for one
