提出并设计了一种Marx发生器线路,将电路模拟和实验验证结果与传统的Marx线路进行了比较,结果表明,所设计的线路通过保证Marx后级开关上的过电压幅值,来保证开关可靠击穿并减小开关自击穿所需时间,从而减小Marx发生器的抖动和增大工作范围.在此线路基础上,设计了一种用于直线感应加速器脉冲功率系统的Marx发生器,该发生器采用正负双极性直流充电,使用低抖动的场畸变火花隙开关作为脉冲形成开关,最大储能16.87 kJ,最高输出电压450 kV,在一定工作状态下可以达到亚纳秒级的时间抖动.

This paper describes a circuit of Marx generator, and compares it with the conventional layout by simulation and experiment. The result indicates that the designed circuit can maintain the voltage between the latter stage switches during the discharging phase of Marx generator, which makes sure the latter stage switches can breakdown reliably and further leads to a small time jitter. A Marx generator used in the linear induction accelerator has been designed and constructed based on this circuit. Its maximal energy storage is 16.87 kJ, and the maximal output voltage is 450 kV. By using low jitter spark gap switches and charged with positive and negative polarities, the Marx generator can operate with subnanosecond jitter.
