Abstract

A power conversion apparatus includes a power converter, a voltage detector, a current detector, a detection voltage adjustor, and a controller. The power converter is configured to convert power from a power source into alternating-current power and is configured to output the alternating-current power to a power system. The voltage detector is configured to detect a voltage of the power system. The current detector is configured to detect a direct-current component of a current between the power converter and the power system. The detection voltage adjustor is configured to add a bias corresponding to the direct-current component to the voltage detected by the voltage detector, so as to generate a voltage detection signal, and is configured to output the voltage detection signal. The controller is configured to control the power converter to output an alternating-current voltage corresponding to the voltage detection signal.
