摘要: 分析了Marx发生器与正弦振荡回路组合直接输出方波脉冲的近方波Marx发生器理论，并设计了一个该类型的方波发生器装置。其中,Marx发生器由16个充电电压为100 kV、容值为40 nF的电容器组成，采用正负充电的S型超前触发回路,正弦振荡回路由5个与Marx发生器同类型的电容器和1个0.5 H的电感组成。通过Spice模拟，在负载为100 时，输出脉冲电压为1.1 MV，脉宽约300 ns。提出了利用Marx发生器触发LC回路的方法，以解决Marx与LC回路的同步触发问题，使输出电压能够有效叠加。Abstract: The paper analyzes the high voltage rectangle pulse generator with a Marx generator and a LC circuit in theory, and designs a pulse generator of this kind. The Marx generator is constituted of sixteen 100 kV, 400 nF capacitors, with a pre-triggered S-type circuit. The LC circuit is made by five capacitors the same as that of the Marx generator and a inductor of 1.5 H inductance. The simulation of Spice shows a 1.1 MV, 300 ns, rectangle pulse produced by this pulse generator. The middle stage of the Marx generator is used to trigger the LC circuit in order to synchronize this two parts.
