摘　　要：基于磁压缩和SOS效应原理,设计了一种新型无间隙ns级脉冲电源。通过Pspice电路仿真分析和试验研究,着重探讨了关键参数对输出电压的影响。研究结果表明:电源在前级饱和变压器TV1匝数为1:20,磁压缩电感MS匝数为13,后级升压饱和变压器TV2匝数为2:10时能获得较高的输出电压峰值,负载为50Ω时,脉冲电压峰值-51kV,脉宽120ns,峰值前沿60ns。该电源将在放电等离子体处理环境污染中具有良好的应用前景。A novel nanosecond pulse power based on the theory of magnetic pulse compression and SOS effect was developed.The effect of some key parameters on the pulse power output characteristics were discussed through Pspice simulation and laboratory study.The results show that a 51 kV negative pulse is formed which has a pulse width of 120 ns and steep rise time of 40 ns at a load of 50 Ω,when the turns of MS is 13,and the winding ratio of TV1 and TV2 are 1：20 and 2：10,respectively.The power will have a good application foreground in environmental treatment by discharge plasma.
