A power converter includes a power converter section (4) (e.g., an inverter circuit) having a plurality of switching elements (Sp, Sn) in which a current can flow in a reverse direction, and a control section (10) which determines on-state time of each of the switching elements (Sp, Sn) according to an output voltage of the power converter section (4), thereby switching on/off states of the switching elements (Sp, Sn). The control section (10) instructs the power converter section (4) 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 (Sp, Sn).
