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10～80 kV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。Abstract: 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 than 3 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.
