| Abstract: | Slowly-drop gate voltage and softly turn-off principles are explained in this article, specific parameters are also listed.A particular over-current protection and drive circuit is given ,the impact of resistance between gate and emitter on gate voltage dropping is discussed ,and an adjustable gate-emitter resistance circuit is put forward.On these bases,we obtain a good experimental result. |
