Research on Inductively Isolation Solid State Marx Pulsed Power Source

基于现场可编程门阵列(FPGA)和串联谐振充电电路,设计了一款参数可调、结构紧凑的固态Marx高压脉冲电源。采用FPGA提供时序可调的控制信号,可产生电压幅值、脉宽和频率均可调的高压脉冲。采用串联谐振充电电路作为充电电源,能够更高效快速地对Marx电路充电,且故障状态下具有一定的抗短路能力。实验中搭建了一台12级Marx电路,能稳定输出电压幅值10 kV,重复频率10 kHz,脉宽5μs的高压重频脉冲,且脉冲参数可调。

Based on field programmable gate array （FPGA） and series resonant charging circuit, a high voltage Marx power supply with adjustable parameters and compact structure is designed. The field programmable gate array （FPGA） is used to provide the timing adjustable control signal, which can generate high voltage pulse with adjustable voltage amplitude, pulse width and frequency. The series resonant charging circuit is used as charging power supply, which can be used to charge the Marx circuit more efficiently and quickly. And under the condition of fault, it has the ability of short circuit. In the experiment, a 12 stage Marx circuit is designed, which can stabilize the output voltage amplitude of 10 kV, the repetition frequency 10 kHz, the pulse width of the 5 μs pulse, and the pulse parameters can be adjusted.
