Abstract

In urban rail transit, when the train running, the AC voltage fluctuates, which resulting in the instability of DC side voltage of the rectifier unit. The hybrid traction power supply consists of a 12-pulse rectifier unit and a four-quadrant converter device (4QC). Aiming at the problem of circulation between the rectifier unit and the 4QC unit of the hybrid traction power supply device, the possible causes of the circulation are analyzed. The output voltage characteristics and basic structure and the working principle of the hybrid power supply device are studied. Then putting forward the corresponding anti-circulation strategy, and through simulation and test to verify its effectiveness. And the strategy adjusts the voltage value automatically according to the actual situation without manual operation, which is very practical.
