摘　　要：为了满足在高电压状态下对氧化锌陶瓷（ZnO）元件的检测需要,研制了一种基于脉冲变压器和脉冲形成网络（PFN）的,输出电压范围10-80kV可调,波形为近方波的高压脉冲源。根据实际研制过程,分别介绍了高压脉冲源的设计、仿真及系统电路构建。测试了高压脉冲源在标准负载（匹配）和氧化锌陶瓷负载上的输出情况。结果显示：脉冲顶降小于3%,顶部波动小于1.5%,前后沿指标均满足要求。因而,高压脉冲源可以用于氧化锌陶瓷的性能检测。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 top fluctuation is less than 1.5%,and pulse rising edge and falling edge all meet the requirements.The results show that the high voltage pulse source can be used for performance testing of ZnO ceramics.
