Abstract
An AC-rotating-electric-machine control apparatus includes two or more electric-power conversion circuits that control respective voltages to be applied to the two or more groups of multi-phase armature windings, for each of the two or more groups of multi-phase armature windings; each of the two or more electric-power conversion circuits has two or more switching devices for opening or closing the corresponding group of multi-phase armature windings, for each of the phases; the two or more switching devices are switching-controlled in such a way that opening operation or duty control can be applied to the corresponding group of multi-phase armature windings.
