Abstract
In a first power feeding mode, a controller supplies AC power output by an inverter to a load. In a second power feeding mode, the controller supplies AC power supplied from an AC power supply to the load. The controller switches an operation mode to the first power feeding mode when a voltage drop of the AC power supply is detected during the second power feeding mode. The controller, for a prescribed time period from detection of the voltage drop, causes a converter to perform reverse conversion to convert DC power output by a power storage device to AC power, and controls the reverse conversion in the converter such that an instantaneous value of an AC voltage output from the converter becomes equal to or higher than an instantaneous value of an AC voltage output from the inverter.
