摘要
为提高磁脉冲压缩系统的应用效果,在分析了传统磁脉冲压缩系统的原理、缺点后介绍了省去磁芯复位电路的磁脉冲压缩系统并从原理、压缩过程以及不同的拓扑电路3方面详细分析了单级磁脉冲压缩系统,特别是C3和C4对负载放电过程,给出了等效电路。通过等效电路的仿真解释了续流电感L2对系统的影响;仿真和实验结果的对比验证了电路仿真模型的正确;对于快速恢复二极管替代续流电感的系统电路,仿真与实验结果均表明脉冲尾部的反峰幅值与持续时间都显著减小。
A magnetic pulse compression system is presented which does not contain external remagnetization circuits that are commonly used in magnetic compressors. Principle of operation of the compressor is described. A thorough theoretical analysis of the circuit topology is presented. Equivalent circuits for two consecutive operation stages of the compressor accounting for nonlinear processes in magnetic switches are analyzed. Simulation results illustrate how inductance L2 affects the system. The experimental results obtained with a resistive load are well in agreement with the circuit simulation. To improve the matching,L2 is replaced with fast-recovering HV diode. The simulation and experiment show that the pulse voltage reverse amplitude and damped oscillation duration are reduced drastically.
