Abstract
A DC link has first and second power supply lines. A first rectifying circuit has a plurality of input terminals that input an AC voltage and a pair of output terminals connected to the DC link. An inverter converts a voltage applied to the DC link into another AC voltage. A boost chopper has a capacitor at an output stage. A switch switches discharge and non-discharge from the capacitor to the DC link. In the boost chopper, charge into the capacitor is performed at least at a first period. The first period is a part of a period during which a discharge duty as a time ratio of continuity of the switch is larger than 0.
