摘要
基于磁开关设计了一套两级磁脉冲压缩系统,负载为50电阻时输出电压峰值高达51kV,脉冲宽度120ns,峰值前沿60ns。通过示波器测量出非线性磁芯的磁滞回线,并将其参数导入PSPICE软件中,在给定电路参数下对该系统进行PSPICE仿真,得到的结果与实验结果基本吻合,证明该软件能比较真实地仿真磁芯的非线性特性,利用PSPICE软件来仿真两级磁脉冲压缩系统能对实验起到较好的辅助作用。
Two-stage magnetic pulse compression system based on magnetic switch was developed. A 51 kV negative pulse was formed which had a pulse width of 120 ns and steep rise time of 60 ns. Hysteresis loop of non-linear core was measured with an oscilloscope and then imported to PSPICE. The system was simulated on PSPICE under the given circuit parameters. The simulation result obtained is consistent with the experimental one, proving the real simulation on nonlinear characteristics of the core. It can play a good supporting role in experiment by using PSPICE software to simulate the two-stage magnetic pulse compression system.
