Abstract
An inverter converts a direct-current (DC) power supplied from different DC power supplies into an alternate-current (AC) power formed by a quasi sinusoidal wave and then outputs the thus converted AC power. A first absolute-value setting switch to a fourth absolute-value setting switch are switched to generate absolute values of AC power by using a combination of a power-supply voltage supplied from each DC power supply and a voltage generated from a voltage supplied from each DC power supply. A first polarity setting switch to a fourth polarity setting switch are switched to generate the polarities of AC power. A control unit controls the switching of the first absolute-value setting switch and the like and the first polarity setting switch and the like. The control unit switches the first polarity switching switch and the like with timing at which the polarity of quasi sinusoidal wave changes.
