摘要: 分析了磁开关的工作原理及其工作过程进行了分析，推导了磁开关磁芯体积公式，给出了多级磁脉冲压缩电路所需的条件，使用Pspice对磁开关的工作过程进行了模拟。根据理论分析和数值模拟的结果，设计了一台10 kV级，压缩比为8.3的磁开关，并在实验中将10 kV，9.2 μs的脉冲压缩为10 kV，1.3 μs的脉冲。针对该实验平台设计了一种便捷的磁芯动态磁滞回线测试方法，运用该方法不需搭建测试平台，直接在单级磁脉冲压缩电路平台上即可完成磁芯参数的测量和磁滞回线的绘制。Abstract: A theoretical analysis of the working mechanism and process has been presented for a magnetic switch based on metglas magnetic core. The volume of the magnetic core and the condition for multiple stage magnetic pulse compression circuit were deduced. Then the working process of the magnetic switch was simulated by Pspice. For validation a magnetic switch with 10 kV output voltage and 8.3 compression ratio was designed according to the theoretical analysis and simulation result. The experimental results reveal that the 10 kV, 9.2 μs electric pulse is compressed to 10 kV, 1.3 μs, which is in agreement with the theoretical design. At last, a novel testing method for the hysteresis loop of the magnetic core has been proposed according to this experimental platform. And the hysteresis loop o
