磁脉冲压缩电路的仿真分析

为了提高磁脉冲压缩电路效率并减小体积，使用PSPICE电路仿真软件，采用控制变量的方法，对影响磁脉冲压缩电路的各个因素进行了理论分析和仿真验证。在以纳米晶材料作为磁芯、总压缩比为100、两级磁脉冲压缩电路体积最小的情况下进行了仿真分析。结果表明，脉冲上升时间从6.7μs压缩到67ns，符合脉冲气体激光器对于快放电时间的要求；在负载电阻为250Ω、一级复位电流在1.09A~9.80A、二级复位电流在3.27A~14.50A时，系统效率的最大值为81.9%；负载电阻的取值以及复位电流过大过小都会对效率产生影响。该研究为激光器中磁脉冲压缩电路效率的进一步提升，以及体积的小型化提供了参考。

Simulation analysis of magnetic pulse compression circuit

In order to improve the efficiency of magnetic pulse compression circuit and reduce its volume, by using PSPICE circuit simulation software and using the method of control variables, the factors that affect the circuit were analyzed and simulated. The simulation analysis was carried out when the nanocrystalline material was used as the core, with the total compression ratio of 100 and the volume of the two-stage magnetic pulse compression circuit at the smallest status. The results show that the pulse rise time is compressed from 6.7μs to 67ns, which meets the requirements of pulse gas laser for fast discharge time; when the load resistance is 250Ω, the first reset current is 1.09A~9.80A, and the second reset current is 3.27A~14.50A, the maximum efficiency of the system is 81.9%; the value of the resistance and the reset current too large or too small will affect the efficiency. This study provides a reference for the further improvement of the efficiency of the magnetic pulse compression circuit and the miniaturization of the volume.
