Claim 2:
3. 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 control schemes further include active short-circuit control in which the upper-stage-side switching elements in the arms for all of a plurality of phases are brought into on state or the lower-stage-side switching elements in the arms for all of a plurality of phases are brought into on state, and
in the first speed region, target first speed region control is performed in which 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 pulse width modulation control.
