摘　　要：采用模块化结构,设计了一种卷绕式螺旋形薄膜介质脉冲形成线,并且对绝缘材料、电极材料的选择依据进行了分析。基于模块化卷绕式脉冲形成线,研制的重复频率脉冲方波产生器采用4个开关同步触发四级形成线模块,从而实现多模块的电压串联叠加,以达到产生高压的目的。开关采用气体火花间隙开关,每级开关及充放电采用电感隔离。研制的脉冲产生器输出电压220kV,脉冲宽度182ns,前沿50ns,可10Hz重复频率稳定运行。A modularized layer-wound spiral stripline was designed using polypropylene as insulation material.The performance of the insulation film and the electrode foil was analyzed.A four-stage stacked Blumlein line based on the stripline operating with four gas switches and a resistance load delivers a quasi-rectangular output waveform at the repetitive frequency of 10 Hz.The stages are stacked in series at one end,and charged in parallel and synchronously commuted with the switches at the other end.In this way,relatively low charging voltages are multiplied to give a high discharge voltage across an arbitrary load.The Blumlein line can output 220 kV pulses with durations of 182 ns,and rising times of 50 ns at the repetitive frequency of 10 Hz.
