PROBLEM TO BE SOLVED: To provide a power converter that cna reduce occurrence of serve current and a serge voltage in a prior art.SOLUTION: A power converter has an inductor inserted between a secondary winding and a switching element and an auxiliary switching element inserted between the secondary winding and the switching element in parallel to the inductor. The auxiliary switching element is set to an OFF state in a power supply mode in which the output voltage and output current output from a connection portion have the same polarity, and the auxiliary switching element is set to an ON state in a power regeneration mode in which the output voltage and output current output from the connection portion have different polarities.SELECTED DRAWING: Figure 42 |
