摘　　要：设计了一种基于Marx的三电极脉冲电源。采用磁环隔离驱动方案和双MOSFET驱动电路,实现了在三电极负载下同时输出正负高压脉冲。分析了电路的运行方式,搭建了32级脉冲电源,并设计了一种针板电极和DBD电极结合的三电极负载,实现了总输出电压13 kV,脉宽10μs,频率1 kHz,且输出电压、脉宽可调。实验验证了该电源方案在三电极负载下的可行性。A three-electrode pulse power supply based on Marx is designed.Magnetic ring isolation driving scheme and dual MOSFET driving circuit are adopted to realize the simultaneous output of positive and negative high-voltage pulses under the three-electrode load.Firstly,the operation mode of the circuit was analyzed,a 32-stage pulse power supply was built,and a three-electrode load combined with the pin-plate electrode and DBD electrode was designed.The total output voltage is 13 kV,the pulse width is 10μs,and the frequency is 1 kHz.Meanwhile,the output voltage and the pulse width are adjustable.The feasibility of the proposed power supply scheme under the three-electrode load is verified by experiments.
