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 temperature detecting apparatus includes an integrated circuit that integrates an overheating detecting circuit, a breakage detecting circuit and a disabling circuit, and an element connection terminal connecting a temperature sensing element. The disabling circuit disables the breakage detecting circuit from detecting a breakage of wire when a voltage at the element connection exceeds a disabling threshold which is set higher than an overheating detection threshold and a breakage detection threshold. A predetermined voltage higher than the disabling threshold is applied to the element connection terminal when the temperature sensing element is not connected to the element connection terminal.
