A power storage device is electrically connected to a first input and output end located on the opposite side of a direct-current common section in a second power converter. According to an input form of electric power, a first power converter operates as a DC/AC converter or an AC/DC converter. The second power converter operates as a DC/AC converter, an AC/DC converter, or a DC/DC converter. The power storage device is charged using direct-current power supplied from the direct-current common section or the first input and output end side. The power storage device discharges desired direct-current power to the direct-current common section or the first input and output end side. A control device freely adjusts, according to the input form of the electric power, the voltage of the direct-current common section to a desired voltage including a high voltage or a low voltage.
