Abstract

Helical flux compression generators (HFCG) of a 50 mm form factor have been shown to produce output energies on the order of ten times the seeded value and a typical deposited energy of 3 kJ into a 3 muH inductor. Our previous work with a non-optimized fuse has produced-100 kV into a 15 load, which leads into a regime relevant for high power microwave (HPM) systems. It is expected that-300 kV can be achieved with the present 2-stage HFCG driving an inductive storage system with electro-exploding fuse. In order to optimize the electro-explosive wire fuse, we have constructed a non-explosive test bed which simulates the HFCG output with high accuracy. We have designed and implemented a capacitor based, magnetic switching scheme to generate the near exponential rise of the HFCG. The varying inductance approach utilizes 4 stages of inductance change and is based upon a piecewise linear regression model of the HFCG waveform. The non-explosive test bed will provide a more efficient method of component testing and has demonstrated positive initial fuse results

一种用于爆开开关的流量压缩发生器非爆试验台

50mm形状的螺旋磁通压缩发生器(HFCG)已被证明可以产生10倍于播种值的输出能量，并且典型的沉积能量为3kj，进入3muh的电感。我们之前使用的非优化保险丝在15负载中产生了-100千伏，这导致了与高功率微波(HPM)系统相关的状态。利用现有的两级HFCG驱动电爆保险丝感应储能系统，预计可达到-300 kV。为了优化电爆丝引信，我们搭建了一个非爆炸试验台，高精度地模拟了电爆丝引信输出。我们设计并实现了一种基于电容的磁开关方案，以产生接近指数的HFCG上升。变电感方法利用4级电感变化，并基于HFCG波形的分段线性回归模型。非爆炸试验台将提供一种更有效的组件测试方法，并已证明了积极的初始熔丝结果
