Abstract:
A power semiconductor device driving circuit includes a gate control terminal, which is provided at a position separated from a drain terminal of a power semiconductor device by a predetermined distance so that electric discharge is generated between the drain terminal and the gate control terminal at the time of generation of surge. A surge voltage is applied to the gate control terminal due to this discharge, the gate of the power semiconductor device is charged to turn on and absorb the surge energy. Thus it becomes possible to suppress the surge voltage applied to the drain terminal and prevent breakdown of the power semiconductor device.
