Abstract
A power conversion apparatus includes: a rectifying unit that rectifies a power-supply voltage applied from a commercial power supply; a capacitor connected to an output end of the rectifying unit; an inverter that converts DC power output from the capacitor into AC power and outputs the AC power to a device on which a motor is mounted; a voltage detecting unit that detects the power-supply voltage; and a control unit that performs pulsation compensation control of reducing a pulsatile component of a capacitor current that is a charge and discharge current of the capacitor on the basis of a detection value by the voltage detecting unit.
