摘 要: | 选用雪崩三极管作为开关器件,详细讨论了设计和优化Marx电路的方法;将Marx电路进行模块化改进,设计了一种新型四路同步叠加立体结构,并得出了叠加倍数与模块数量的理论关系式。最终,利用+300V直流电源供电,通过四路输出幅值为-2.6kV的Marx模块叠加,在50Ω阻性负载上得到了幅值-5.0kV、半高脉宽5.3ns、脉冲能量约2.0mJ的高斯型脉冲,时延抖动小于100ps,重复频率达10kHz,叠加效率达96.2%。调节直流偏置电压为200~300V,并配合模块数量的增减,可调节脉冲幅值为1.6~5.0kV。

Abstract: | In this paper, utilizing avalanche transistors as switching devices, the methods of designing and optimizing Marx circuit were discussed in detail. Modular improvement was implemented to the Marx circuit and a novel stereo structure of synchronous four-module combining was designed. The theoretical relation of the combining ratio and the combined modules were derived. Using a +300 V DC power and combining four -2.6 kV Marx modules, Gaussian pulses were obtained on a 50 resistive load with -5.0 kV magnitude, 5.3 ns half peak width, 2.0 mJ single-pulse energy. It was realized to stably work under a repetitive frequency of 10 kHz and the time delay jitter was measured less than 100 ps. The four-module combining efficiency was calculated up to 96.2 %. If changing the DC bias voltage between 200 V and 300 V and varying the number of combined modules, the final output magnitude would be regulated from 1.6 kV to 5.0 kV. |
