PROBLEM TO BE SOLVED: To more sufficiently treat when there is a thermal conversion request for drive power of a motor.SOLUTION: A drive assembly carries out switching of a plurality of switching elements by generating PWM signals for the switching elements on the basis of a percentage modulation of voltage and a voltage phase according to a torque command of a motor, and a pulse number per unit cycle of electric angle of the motor. When there is a thermal conversion request for drive power of the motor, the PWM signals for the switching elements are generated so that a total loss of the motor and an invertor become larger than when there is no thermal conversion request.SELECTED DRAWING: Figure 4

    【課題】モータ(電動機)の駆動電力の熱変換要求があるときに、より十分に対処する。【解決手段】モータのトルク指令に基づく電圧の変調率および電圧位相と、モータの電気角の単位周期当たりのパルス数と、に基づいて複数のスイッチング素子のPWM信号を生成して複数のスイッチング素子のスイッチングを行なうものにおいて、モータの駆動電力の熱変換要求があるときには、熱変換要求がないときに比して、モータおよびインバータの合計損失が大きくなるように複数のスイッチング素子のPWM信号を生成する。【選択図】図4
