使用有限驱动电压的半导体开关器件驱动电路

Semiconductor switching device drive circuit using a limited drive voltage
Abstract:
One of first and second switching devices turns on to flow a current along a current path between a potential reference output terminal of a drive-target switching device and a control terminal of the drive-target switching device to turn on the drive-target switching device. Thereby, a voltage changes between the control terminal of the drive-target switching device and the potential reference output terminal of the drive-target switching device to turn off the one of the first and second switching devices being turned on. Thereby, a potential of the control terminal of the drive-target switching device is clamped.
