Abstract
Disclosed is an inverter having improved power conversion efficiency. The inverter () converts direct current power supplied from a plurality of direct current power supplies (V, V) having different voltages into alternating current power. The inverter () is provided with a control unit (). The control unit () generates modified sine waves using a power supply voltage (E) of the power supplied from the first direct current power supply (V), a power supply voltage (E) of the power supplied from the second direct current power supply (V), and a potential difference (E−E) between the two power supply voltages. The control unit () generates the modified sine waves by controlling H bridge circuits provided for the direct current power supplies (V, V), respectively.
