摘要: 提出了一种基于卷绕型带状线和感应电压叠加器的重复频率脉冲电子束加速器的技术方案。介绍了一台感应电压叠加器感应单元的结构设计，并建立相应的电路模型，对其响应特性进行了模拟研究。介绍了卷绕型带状线的设计原理，制作了一台输出阻抗约3 Ω、脉冲宽度约230 ns的固态化卷绕型带状脉冲形成线。利用该脉冲发生器作为馈源，对感应电压叠加器感应单元的响应特性进行了实验研究，表明感应单元响应良好。对4级感应电压叠加器分别进行了单次脉冲和5 Hz重复频率的实验研究，结果表明叠加器的输出电压约为输入电压幅值的4倍，电流效率约80%，重复频率条件下，脉冲序列重复性较好。Abstract: A technical solution for high power pulse generator which is based on both induction voltage adder (IVA) and rolled strip line is introduced. The induction cell is designed for a 10-stage IVA, its equivalent circuit is obtained and corresponding simulation research is carried out. To study the response characteristics of the induction cell, a rolled strip pulse forming line with an impedance of 3 Ω and pulse duration of 230 ns is fabricated as the voltage drive source. Experimental investigations on both the single induction cell and 4-stage IVA are carried out. The results show that the cell has good response characteristics. The current efficiency of the 4-stage IVA can reach about 80%, and the output voltage is about 4 times the magnitude of the input. In the repetitive condition, the
