摘要: 利用碳酸钡基材料研制了一种环形脉冲形成线。对脉冲形成线的材料特性、电场分布对耐压影响进行分析和研究，通过优化结构设计、材料特性，提高了环形脉冲形成线的耐压水平。利用此脉冲形成线建立了37级Marx发生器，此发生器通过电感进行并联充电和串联放电工作。使用电磁仿真软件对系统结构进行了三维电场分析，分析结果表明, 采用此环形脉冲形成线能够实现同轴设计，电场更加均匀，确定了满足紧凑化的最佳外形尺寸。实验结果表明, 设计的脉冲功率驱动源在充电电压为±19 kV的条件下，在二极管负载下得到了输出半高宽为65 ns、电压为680 kV的快高压脉冲。Abstract: The ring pulse forming line which uses BaTiO3 material is developed. Material characteristics and the influence of electric field distribution on the electric strength of the pulse forming line are analyzed. Due to optimizations of structure design and material characteristics, the electric strength of the pulse forming line has been enhanced. A 37-stage compact Marx generator is designed based on the pulse forming line. The electric field intensity distributions of the configuration with inductances were simulated. According to the results of the simulation, the electric field of the configuration is uniform and gives an optimized contour dimension. In the experiment, when the PFL was charged at ±19 kV, the output voltage was more than 680 kV and the pulse width was about 65 ns on the matching load.
