电爆炸丝和脉冲变压器驱动低阻抗负载研究

对脉冲放电电路中金属丝发生电爆炸后产生的高压脉冲驱动脉冲变压器在低阻抗负载(19Ω)上产生的电脉冲进行了研究,利用Ansoft Simplorer7软件建立了模块化集中参数电路模型,得到了与实验吻合的计算结果。初步研究表明,电爆炸丝驱动脉冲变压器在低阻抗负载上不能产生超高压脉冲,但可显著展宽负载得到的电压脉宽,在需要长脉宽应用场合有潜在的应用前景。

The Investigation of the Pulse over Low-impedance Load Excited by Electric Exploding Wire and Pulse Transformer

This paper has investigated the electric pulse over the low-impedance load(19 Ω)generated by the pulse transformer driven by the electric exploding wire(EEW).It has built a lump-parameter circuit model by the Ansoft Simplorer 7 code to simulate the circuit behavior and got the simulation results which agree with the experimental results well.The preliminary investigation shows that the pulse transformer driven by the EEW is impossible to generate super-high voltage pulse on lowimpedance load,but the transformer can extend the pulse width obviously.This behavior has the potential to be used in the situation which needs long width pulse.
