    • 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.
    • 旋转电机控制装置包括目标电流值计算部,PWM信号生成部,电压施加部和控制部。 目标电流值计算部分计算提供给旋转电机绕组的电流的目标电流值。 PWM信号生成部基于目标电流值生成各绕组的PWM信号。 电压施加部分基于PWM信号向各个绕组施加电压。 当控制部分停止驱动旋转电机时,PWM信号产生部分产生PWM信号,其中至少一个相位的PWM信号中的脉冲变化的定时与PWM信号中的脉冲变化的定时不同 其他阶段。
