摘要： A discharge control device in an electric power conversion system mounted to a motor vehicle turns off a relay in order to instruct an electric power conversion circuit to supply a reactive current into a motor generator, and thereby to decrease a capacitor voltage to a diagnostic voltage. After this process, the discharge control device outputs an emergency discharging instruction signal dis in order to turn on both power switching elements at high voltage side and a low voltage side in the electric power conversion circuit. This makes a short circuit between the electrodes of the capacitor in order to discharge the capacitor, and executes a discharging control to detect whether or not an emergency discharging control is correctly executed and completed. The discharge control device detects whether or not the electric power stored in the capacitor is discharged on the basis of the voltage of a voltage sensor.

摘要： A drive unit controls the operation of a corresponding power switching element such as IGBT which forms an inverter and a converter. The drive unit controls the operation of the corresponding power switching element to supply an operation current to a motor generator. First and second switching elements in the drive unit are simultaneously turned on when an operation signal transferred from a control device is switched to a turning-on instruction operation signal. The voltage at the gate terminal of the power switching element is shifted to a divided voltage obtained by dividing a voltage of the power source by first and second resistances connected in series in the drive unit. When a mirror time period of the power switching element is elapsed, the second switching element only is turned off in order to shift the gate voltage of the power switching element to the voltage of the power source.
