ABSTRACT:
A current detector unit has a current detecting portion detecting a current flowing between a three-phase inverter and a direct-current power supply as a detection current; a three-phase current detecting portion for detecting a three-phase current of the inverter based on the detection current; and a judging portion judging, based on the detection current, whether or not a target time point belongs to a period during which the three-phase current can be detected. If the judging portion judges that the target time point belongs to the period, the three-phase current detecting portion detects the three-phase current.
