Abstract
A power converter includes a power converter section () (e.g., an inverter circuit) having a plurality of switching elements (S, S) in which a current can flow in a reverse direction, and a control section () which determines on-state time of each of the switching elements (S, S) according to an output voltage of the power converter section (), thereby switching on/off states of the switching elements (S, S). The control section () instructs the power converter section () to perform synchronous rectification, and corrects the on-state time according to a drop of an on-state voltage of each of the switching elements (S, S).
