In order to solve the problems existing in metro auxiliary power supply
this paper analyzed a novel metro auxiliary power supply.It was found that a balancing reactor should exist between the upper and lower bridges of the converter in the auxiliary power supply to keep the unbalanced output voltage within an allowable range.Both theoretical analysis and simulation prove that rationally designed leakage reactance of the primary winding can play a role of balancing reactor.It is expected that this study can benefit the similar problems existing in other power supplies.
