ABSTRACT:
A current detecting unit detects three phase current of a three-phase inverter from current flowing between the inverter and a DC power supply. The current detecting unit includes a specified voltage vector generating portion that generates a specified voltage vector indicating a voltage vector that three-phase voltage of the inverter should follow, and a specified voltage vector correcting portion that corrects the generated specified voltage vector. The inverter is controlled in accordance with the specified voltage vector after the correction.
