Train VVVF inverter output voltage characteristics

Propulsion inverters (VVVF Inverter)｜Transportation Systems

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. In addition,

The Conductor of Current: VVVF Control Explained

This is achieved by maintaining a constant ratio between Voltage (V) and Frequency (f). If the frequency increases to speed up the train, the voltage must also increase
