电感变化率对爆炸磁频率发生器性能的影响

Influences of inductance reducing rate in explosive magnetic frequency generators

基于等效电路原理,分析了电感变化率对爆炸磁频率发生器中工作电流的影响。计算表明容性负载导致电流以振荡方式存在。如果电感以比线性更快的方式减小,振荡电流的包络呈"鱼形",而且更有利于电流频率的提高。

Influences of inductance reducing rate on the working electric current induced in the explosive magnetic generators of frequency （EMGF） are analyzed within the framework of their equivalent circuit. It is shown that the employment of a small capacitive load will result in an oscillating electric current in the EMGF. Numerical calculations reveal that when the inductance diminishes faster than a linear one,the envelope of the oscillating current will take a ＂fish＂ shape,and this makes it more advantaged for improving the frequency signature of the current.
