Abstract
Two inverters () provided at respective both ends of open-end windings () are appropriately controlled. As control regions (R) of a rotating electrical machine (), a first speed region (VR) and a second speed region (VR) in which the rotational speed of the rotating electrical machine () is higher than in the first speed region (VR) for the same torque are set, and in the second speed region (VR), a rotating electrical machine control device () controls both inverters (), a first inverter () and a second inverter (), by mixed pulse width modulation control in which control is performed such that a plurality of pulses with different patterns are outputted during a first period (T) which is a half cycle of electrical angle, and an inactive state continues during a second period (T) which is the other half cycle.
