摘要： An electronic control unit includes a substrate, a semiconductor module, a heat storage body, an insulator, and a heat sink. The substrate includes a wiring and a land. The semiconductor module includes a semiconductor chip working as a switching element, a terminal electrically coupled with the semiconductor chip and the wiring, a molded resin sealing the semiconductor chip and the terminal, and a heat radiation plate having a surface exposed from the molded resin and transferring heat generated at the semiconductor chip. The heat storage body has a heat capacity required to store the heat generated at the semiconductor chip. The heat storage body is coupled with the heat radiation plate. The insulator is in contact with the heat storage body or the semiconductor module. The heat sink is in contact with the insulator.

摘要： 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.
