Abstract
At least one first power converter of a plurality of power converters has a charging mode and a standby mode, the charging mode being a mode of converting AC power supplied from an AC power supply through a switch into DC power and storing the DC power in a corresponding power storage device, the standby mode being a mode of generating a control signal for power conversion and awaiting the power conversion. When an AC voltage supplied from the AC power supply is normal, a controller turns on the switch and alternately switches the at least one first power converter between the charging mode and the standby mode. When the AC voltage is not normal, the controller turns off the switch and controls the plurality of power converters such that each of the plurality of power converters converts DC power of the power storage device into AC power and supplies the AC power to a load.
