Chopping-peaking开关形成高功率超宽带双极脉冲的实验研究

 设计研制了一种chopping-peaking组合开关型高功率双极脉冲形成装置，通过调节两个开关的导通时刻来得到不同形状的双极脉冲。理想情况下，形成的双极脉冲电压峰-峰值等于入射脉冲峰值电压的2倍，实验中入射脉冲峰值电压为205kV的单极脉冲，获得了最大峰-峰电压为360kV的双极脉冲，是入射脉冲峰值电压的1.76倍。双极脉冲的持续时间可以改变，最大值为单极脉冲的脉宽。入射脉冲上升时间越小，得到的双极脉冲峰-峰电压就越大。

Generation of high power ulta wide-band bipolar pulse with chopping-peaking switch

This paper presents the chopping-peaking type high power bipolar pulse former, and studies its operating principle.The bipolar pulses with different forms are gained through adjusting the conduction time. 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. By tuning the gaps of chopping switch and peaking switch properly, the highest peak-peak voltage of 360kV is obtained with the injecting voltage of 205kV. The duration of the bipolar pulse can be changed,it's maximum is equal to the width of the injecting pulse.The steeper the injecting pulse,the higher the peak-peak voltage of the generated bipolar voltage pulse.
