To test character of ZnO ceramics resistor undergoing high-voltage,a high-voltage pulse generator whose output pulse is approximately square and voltage amplitude varies between 10-80 kV was designed adopting pulse transformer and pulse forming net(PFN).The article introduces the principle,simulation,circuits of the high-voltage pulse generator,and elaborates output states of the power supply with a standard ZnO load.Test results show that the fall on the top of the waveform is less than3 percent,the pulse ...
