Abstract:
1. A control apparatus for controlling driving of a three-phase rotary machine having two three-phase winding sets, the control apparatus comprising: two drive systems of power converters provided in correspondence to the two three-phase winding sets to output AC currents to the two three-phase winding sets, the AC currents having same amplitude each other and a phase difference of (30±60×n)° therebetween, with “n” being an integer; and a controller unit for controlling output of the three-phase rotary machine, wherein the controller unit superimposes on a base wave current, which is an AC current and a main component of an output of the three-phase rotary machine, fifth harmonic currents of a frequency of as high as fivefold of the base wave current and of a same amplitude to the two three-phase winding sets, thereby reducing a peak value of the base wave current.
