摘要： 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.

摘要： An apparatus is provided to drive a voltage controlled switching element having a conduction control terminal. In the apparatus, it is determined whether or not voltage at the conduction control terminal is at a first voltage which is lower than a second voltage and which is equal to or more than a threshold voltage. The second voltage is a voltage provided when the switching element is in a normal on-state thereof. The threshold voltage is voltage at which the switching element is switched on. When it is determined that the voltage at the conduction control terminal is at the first voltage, the switching element is forcibly switched off.
