Claim 9:
10. The rotating electrical machine control device according to claim 1, wherein
in the first inverter and the second inverter, each arm for one alternating current phase includes a series circuit of an upper-stage-side switching element and a lower-stage-side switching element,
the mixed pulse width modulation control includes mixed continuous pulse width modulation control in which during the second period, control is performed such that an inactive state continues, and during the first period, pulse width modulation is continuously performed for all of the arms for a plurality of phases; and mixed discontinuous pulse width modulation control in which during the second period, control is performed such that an inactive state continues, and during the first period, 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 second speed region on a low speed side in the second speed region, both of the inverters, the first inverter and the second inverter, are controlled by the mixed continuous pulse width modulation control, and
in a high-speed side second speed region on a high speed side in the second speed region, both of the inverters, the first inverter and the second inverter, are controlled by the mixed discontinuous pulse width modulation control.
