Abstract

See full text

A power conversion device includes: a power conversion circuit connected to a direct-current power supply and a power system and configured to perform conversion between direct-current power and alternating-current power; a phase-locked loop circuit configured to output a phase instruction value based on a system alternating-current voltage phase of the power system; and a control circuit configured to control the power conversion circuit based on the phase instruction value from the phase-locked loop circuit. The phase-locked loop circuit includes: a phase difference calculation section configured to calculate a phase difference in a predetermined cycle, the phase difference representing a deviation of the phase instruction value from the system alternating-current voltage phase of the power system; a phase difference correction section; and a phase instruction value generation section configured to output the phase instruction value based on an output of the phase difference correction section.
