Abstract
A power conversion apparatus includes an inductor inserted between a secondary winding and a switching device, and an auxiliary switching device inserted between the secondary winding and the switching device in parallel to the inductor. The auxiliary switching device is in an off state in a power supply mode in which an output voltage and an output current of a connector have the same polarity. The auxiliary switching device is in an on state in a power regeneration mode in which the output voltage and the output current of the connector have different polarities.
