The discharge control is performed to discharge a capacitor connected in parallel to the switching elements when an abnormal event occurs. The discharge control apparatus is configured to simulate the operation of the switching elements assuming occurrence of the abnormal event, and transmits a plurality of signals representing the simulation result to a control device via a common photocoupler that isolates the switching elements side and the control device side. The control device diagnoses whether or not a fault occurs in the discharge control or the like by the simulation result.

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： A drive circuit is used for driving a switching element. The drive circuit includes a detection unit and an integrated circuit. The detection unit detects a state of a controlled switching element and outputs a voltage signal corresponding to a detection result of the state. The integrated circuit receives the voltage signal via an input terminal for the detection result and controls the switching element based on the received voltage signal. The input terminal includes at least two input terminals that are connected to each other so as to receive the same voltage signal from the detection unit.

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.

摘要： A drive circuit for a switching element includes a constant-current control unit and a restriction unit. The constant-current control unit performs a constant-current control for charging an open/close control terminal of a switching element to be driven which is a voltage-controlled switching element with electric charge for turning on the switching element. The restriction unit restricts, to a reference voltage, a voltage between the open/close control terminal and a first end of a pair of ends of a current flow path of the switching element for a predetermined period following a start of the constant-current control within a charging process period during which the open/close control terminal is charged with the electric charge such that the switching element is turned on.
