Abstract

See full text

A power conversion device includes a power conversion circuit, a memory, a voltage detection circuit, a current detection circuit, and a control circuit. The power conversion circuit controls a switching device based on a switching pulse signal to convert direct current power into alternating current power and output the alternating current power to a power supply target. The memory stores an alternating current phase difference. The voltage detection circuit detects an alternating current voltage effective value. The current detection circuit detects an alternating current effective value. Based on the alternating current phase difference, the alternating current voltage effective value, and the alternating current effective value, the control circuit stops output of the switching pulse signal at a time when an alternating current has a value of 0.
