Abstract
This invention provides a power conversion circuit control apparatus which rapidly detects the voltage amplitude and phase of each phase, corrects the output of a current controller by the mean voltage amplitude and mean phase, and corrects, on the basis of the voltage amplitude and phase of each phase, a voltage amplitude command and voltage phase command to be applied to pulse width modulation. The apparatus can suppress an overcurrent even when the AC voltage is unbalanced, and restart the operation without generating any overcurrent when the circuit is to be reactivated.
