摘要： In an electric power conversion system having a discharge control device capable of discharging a voltage charged in a capacitor to a voltage of not more than a predetermined voltage, a linear regulator decreases a voltage of the capacitor and outputs the decreased voltage to a drive unit at a bottom arm in a U phase. A flyback converter for discharging use inputs an output of the linear regulator, and outputs electric power to a drive unit at an upper arm in the U phase. When detecting that own vehicle collides with an obstacle, the discharge control device starts to execute discharge control of the capacitor by turning off a photo coupler and turning on the linear regulator.

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 electronic system has IGBT, on driving FET and off driving FET connected with the gate of the IGBT, and a control circuit. The on driving FET in an on state supplies electric charge to the IGBT gate. The off driving FET in an on state releases the charge from the GET gate. The control circuit controls each of the on FETs according to a driving signal to be set in the on and off states every switching period of time and to control the voltage at the IGBT gate. When on-failure occurs in the on driving FET set in the on state so as to keep the on driving FET in the on state in spite of control of the control circuit, the control circuit controls a controlled element other than the off driving FET to set the IGBT in the off state.
