POWER CONVERSION DEVICE AND PROGRAM

WIPO Patent Application WO/2023/105602

A1

This power conversion device comprises a conversion unit, a voltage control unit, a phase control unit, a modulation unit, and a limiting unit. The conversion unit converts the DC power output from a power source into AC power and outputs the AC power. The voltage control unit generates an amplitude command for changing the amplitude of the output voltage by performing system formation control for maintaining the amplitude of the output voltage from the conversion unit at a predetermined value on the basis of a feedback signal of the output from the conversion unit. The phase control unit generates a phase command for changing the phase of the output voltage by performing system formation control for maintaining the phase of the output voltage at a predetermined value on the basis of the feedback signal. The modulation unit changes the amplitude and phase of the output voltage on the basis of the amplitude command and the phase command. When the output current from the conversion unit is greater than a first threshold, the limiting unit performs a process for stopping the system formation control in the voltage control unit and a process for reducing the amplitude of the output voltage.
