摘要: 介绍了一种采用半导体开关与磁开关、可饱和脉冲变压器相结合技术的固态脉冲电源，此电源可用于脉冲放电等离子体烟气治理。在理论分析的基础上建立了实验模型，通过实验验证了此类电源的可行性，解决了8支晶闸管开关串联的动静态均压及开通同步性问题，并对可饱和脉冲变压器及磁开关的工作特性进行了分析计算。电源在阻性负载上得到峰值电压37.5 kV、前沿101 ns、脉宽1 μs的脉冲，重复频率300 Hz，输出功率10 kW。Abstract: The paper presents a solid-state pulsed power generator, which is based on the integrated technology of semiconductor switch, magnetic switch and saturable pulse transformer. This pulsed power generator is used for pulsed plasma induced chemical process(PPCP) . Based on the theory analysis, the trial model is set up. The results of the experiment testify the feasibility of the generator. The experiment solves the static and dynamic voltage-equilibrium problem and the conduction synchronization of 8 thyristors in series. The working properties of saturable pulse transformer and magnetic switch are analyzed and calculated. The main parameters of the generator are as follows: peak voltage 37.5 kV with resistance load, pulse rise time 101 ns, pulse width 1 μs, repetition frequency 300 Hz, and
