    • A drive device has a break circuit. The break circuit inputs phase-current values transferred from phase-current sensors mounted on an electrical path of a motor generator. A power switching element is equipped with a freewheel diode connected in parallel with each other. An inverter has pairs of the power switching elements. In each pair, the power switching element in a high voltage side and the power switching element in a low voltage side are connected in series. It is detected for the freewheel diode to be in a freewheel mode when a forward current flows in the freewheel diode. The break circuit detects the freewheel mode where the current flows in the freewheel diode in a lower arm when the phase-current value is not less than a predetermined threshold value. The break circuit detects the freewheel mode where the current flows in the freewheel diode in an upper arm when the phase-current value is not more than the threshold current value.
    • 驱动装置具有断路电路。 断路电路输入从安装在电动发电机的电路上的相电流传感器传送的相电流值。 功率开关元件配备有彼此并联连接的续流二极管。 逆变器具有成对的功率开关元件。 在每对中,高压侧的功率开关元件和低压侧的功率开关元件串联连接。 当正向电流流过续流二极管时,检测到续流二极管处于续流模式。 当相电流值不小于预定阈值时,断路电路检测电流在下臂中的续流二极管中流动的续流模式。 当相电流值不大于阈值电流值时,断路电路检测电流在上臂中的续流二极管中流动的续流模式。
