Abstract: In a power converter, a DC bus is supplied with a DC power from a voltage conversion circuit for regulating a voltage of a power output from a DC power supply, a voltage of the DC power being regulated by the voltage conversion circuit. An inverter converts a DC power on the DC bus into an AC power and supplies the AC power as converted to a power system. A controller controls the inverter. When it is necessary to suppress an output, the controller suppresses the AC power supplied by the inverter to increase a voltage on the DC bus.
