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.

A first wiring pattern electrically connecting the feedback rectification circuit and the control circuit is formed in one of two surface regions of the wiring board separated by an imaginary line running through a junction of the first wiring pattern and the feedback rectification circuit and a junction of the first wiring pattern and the control circuit, and a second wiring pattern electrically connecting the control circuit and the switching element is formed outside an area enclosed by the imaginary line and the first wiring pattern.
