Abstract
A power conversion apparatus includes a rectification unit that rectifies a first alternating-current power supplied from a commercial power supply; a capacitor connected to output terminals of the rectification unit; an inverter that is connected across the capacitor, converts power output from the rectification unit and the capacitor into a second alternating-current power and, outputs the second alternating-current power to a load including a motor; and a control unit that performs operation control on the inverter to cause the second alternating-current power that includes a pulsation based on a pulsation of power that flows into the capacitor from the rectification unit to be output from the inverter to the load, to restrain a current that flows into the capacitor.
