新型爆磁压缩脉冲功率调制电路

爆磁压缩发生器一般具有较低阻抗,在驱动较高阻抗负载时需要脉冲功率调制电路。传统的脉冲功率调制电路需要脉冲变压器,体积庞大,若其后再采用传输线作中间电容储能,尽管输出波形有改善,但体积更大。提出一种无需脉冲变压器,把传输线当作电感储能元件的功率调制电路。该方案具有电路结构简单、体积紧凑、绝缘压力小等优点。文中同时给出了电路的仿真结果。该功率调制方案将使爆磁压缩的应用更加广泛。

A Novel Power Conditioning Circuit for Flux Compression Generators

A novel power conditioning circuit for flux compression generators (FCG) to drive high impedance loads is presented. FCG usually has very low impedance, and power conditioning is necessary with high impedance loads. The traditional power conditioning scheme uses a pulse transformer and sometimes an additional capacitive pulse forming line (PFL) to improve the output waveform, making the system bulky. The paper introduces a circuit without transformers, using PFL as an inductive energy storage unit. This scheme has the advantages of simplicity, compactness, and easy insulation. Numerical simulation is shown to prove the concept. By using this circuit FCG will have wider applications.
