Claim:
1. A power converter for converting electric power between a power source and a load, comprising: a voltage changing device including a rectifier configured to prevent a backflow of a current from a load to a power source, the voltage changing device being configured to change a voltage of electric power supplied from the power source to a predetermined voltage; and a commutation device including the commutation device includes a transformer configured to apply a voltage, induced by a current flowing through a primary-side winding of the transformer, to a secondary-side winding of the transformer on the other path, and a turns ratio between the primary-side winding and the secondary-side winding of the transformer is adjusted so that the current generating a voltage causing reverse recovery of the rectifier flows through the commutation device while making a return current flowing on a side of the primary-side winding smaller than a current capacity of each element connecting to the primary winding, wherein the transformer includes a reset winding provided to the primary-side winding.
