Claim 4:
5. The rotating electrical machine control device according to claim 3, or wherein
the pulse width modulation control includes, as the control schemes, continuous pulse width modulation control in which pulse width modulation is continuously performed for all of the arms for a plurality of phases; and discontinuous pulse width modulation control in which pulse width modulation is performed including a period during which switching elements in one of the arms for one of a plurality of phases are fixed to on state or off state,
in a low-speed side first speed region on a low speed side in the first speed region, one of the inverters, the first inverter or the second inverter, is controlled by the active short-circuit control, and an other one of the inverters is controlled by the continuous pulse width modulation control, and
in a high-speed side first speed region on a high speed side in the first speed region, one of the inverters, the first inverter or the second inverter, is controlled by the active short-circuit control, and an other one of the inverters is controlled by the discontinuous pulse width modulation control.
