摘　　要：介绍了采用C-P组合开关产生双极脉冲和采用Blumlein线产生双极脉冲两种高功率双极脉冲产生技术,理想情况下,这两种双极脉冲形成线产生的双极脉冲电压峰-峰值均等于入射脉冲峰值电压的2倍。设计了相应的高功率双极脉冲形成线,并采用Pspice软件对形成线进行了模拟计算。在同一台高功率超宽带单极脉冲源上,分别对这两种双极脉冲形成线进行高压实验研究,结果为:C-P组合开关双极脉冲形成线在入射脉冲电压为855.5 kV、脉宽为2.1 ns的情况下,可以产生负峰电压为812.0 kV、正峰电压为603.2 kV、半周期为720 ps的双极脉冲,峰-峰值电压是入射脉冲峰值电压的1.65倍。Blumlein双极脉冲形成线在入射脉冲电压为652.0 kV、脉宽为2.1 ns的情况下,可以产生负峰电压为571.9 kV、正峰电压为550.4 kV、半周期为740 ps的双极脉冲,峰-峰值电压是入射脉冲峰值电压的1.72倍。The paper presents Chopping-Peaking（C-P） switch type and Blumlein line type high power bipolar pulse formers, and studies their operating principles. In ideal condition, the output bipolar high voltage pulses with the peak-peak voltage between the peaks of unlike polarity is twice the voltage of the injecting pulse. Two corresponding high power bipolar pulse formers are designed and simulated calculations are carried out through adopting Pspice software. High voltage experiments about two types of high power bipolar pulse formers are operated on the same high power ultra-wideband supply and the results of the experiments are that the C-P switch type bipolar pulse former can export the bipolar pulse with peak voltages of -812.0 kV, 603.2 kV and 720 ps interval of two peaks, at the input pulse with 855.5 kV peak voltage and 2.1 ns width. And the Blumlein line type bipolar pulse former can export the bipolar pulse with peak voltages of -571.9 kV, 550.4 kV and 740 ps interval of two peaks, at the input pulse with 652.0 kV peak voltage and 2.1 ns width. The peak-peak voltage of the bipolar pulses is 1.65 and 1.72 times the voltage of the injecting pulse, respectively.
