Review of high power compact pulse forming network-Marx generators

PFN-Marx发生器可同时实现升压和脉冲形成,具有紧凑的基因。特别是近年来脉冲储能技术的发展,使得直接利用PFN-Marx发生器驱动各类负载成为现实,因而PFN-Marx发生器逐渐成为国内外研究热点。对国内外的高功率紧凑PFN-Marx发生器的研究进展进行了系统介绍,评述其参数和结构特点。通过总结,从时间发展历程上看,PFN-Marx发生器采用高储能密度器件,装置的储能密度水平在不断地提高,尺寸紧凑化水平也在提高;在追求紧凑化的手段上,PFN-Marx发生器的空间结构的优化设计效果优于PFN网络拓扑参数的优化设计;PFN-Marx发生器采用波形优化方法具有较明显的收益,可有效降低装置紧凑化带来级间分布参数更强耦合的负面影响。同时论文探讨了PFN-Marx发生器的发展趋势,为PFN-Marx发生器的研究和技术路线探索提供参考和依据。

The pulse forming network(PFN)-Marx generator can realize both integration of pulse modulation and pulse voltage accumulation,exhibiting a the natural“gene”of compactness.In recent years,the pulsed energy storage technology has been developing rapidly,which makes it a reality to use PFN-Marx generators to drive various loads directly.The PFN-Marx generator has gradually become a worldwide research focus.The research progress of high-power compact PFN-Marx generators are systematically introduced in this paper.In summary,judging from the development over time,PFN-Marx generators adopt high-energy-density components and thus improve the energy density level themselves,which makes the generator more and more compact.In the pursuit of compactness,the effect of optimal design of PFN-Marx generator spatial structure is better than optimal design of PFN network topology parameters.The waveform optimization method of the PFN-Marx generator has obvious benefits,which can effectively reduce the negative impact of stray parameters strongly coupling between stages caused by small size of generator.In the meanwhile,this paper discusses the development trend of PFN-Marx generator.
