| 摘 要： | 为满足某强电磁脉冲辐射系统对轻小型脱离地面脉冲电源的应用需求，研究了一种微型动态级联爆磁压缩发生器。首先介绍了该发生器的结构参数，然后利用基于等效电路的数值计算模型对该发生器电路参数和输入输出电流进行了模拟计算，最后以蓄电池供电的初始能源为发生器提供初始种子电流，对发生器输出特性进行了爆轰实验。实验结果表明，发生器在1.44 μH电感负载上产生脉冲电流峰值达到49 kA，电流上升时间5.2 μs，能量放大约7.8倍。

| Abstract: | To satisfy the application requirement of a high power electromagnetic pulse radiating system to a small light offground pulsed power supply, a miniature dynamic cascaded explosively-driven magnetic flux compression generator is investigated in this paper.Firstly, the structural parameters of the generator are introduced.Then its electrical parameter, input and output current are calculated by utilizing a numerical computation model based on equivalent circuit.The output characteristics of the generator was tested by experiments, in which the seed current was supplied by an initial power source based on a battery.It is found that a current pulse with a peak value of 49 kA and rise time of 5.2μs was generated on an inductive load of 1.44μH, while the energy amplification factor was 7.8. |
