Abstract:
A rotating electrical machine control device includes a target current value calculation section, a PWM signal generation section, a voltage application section, and a control section. The target current value calculation section calculates target current values of electric currents supplied to windings of a rotating electrical machine. The PWM signal generation section generates PWM signals for the respective windings based on the target current values. The voltage application section applies voltages to the respective windings based on the PWM signals. When the control section stops driving of the rotating electrical machine, the PWM signal generation section generates the PWM signals in which a timing of a pulse change in the PWM signal of at least one phase is different from timings of pulse changes in the PWM signals of the other phases.
