Abstract
A power converter, a voltage detector that detects a system voltage at an AC wiring side of the power converter; and a controller that performs power conversion control between AC wiring and DC wiring by transmitting a drive signal to the power converter. The controller includes: a phase calculator that calculates a current phase from the system voltage detected by the voltage detector; a phase jump angle calculator that calculates a virtual phase that follows temporal changes in the current phase in a lagging manner, and calculates a phase difference between the current phase and the virtual phase as a phase jump angle; and a drive signal generator that generates the drive signal to the power converter, which is a signal for adjusting active power that is inputted to/outputted from the power converter so as to suppress the phase jump angle.
