摘要
根据Trigatron的触发要求设计了脉冲变压器型驱动源、三电极气体开关。在多种驱动模式下对三电极开关的自陡化参数进行统计分析,选择最优的自陡化工作模式。通过研究自陡化工作模式,优化了三电极开关工作极性、工作电场、紫外辐照强度和辐照时间。试验结果表明:增加陡化环节后,Trigatron的击穿概率有了明显提高,击穿时刻延迟和抖动明显降低,扩大了Trigatron稳定工作的欠压比范围。
A tri-electrode self-steepening switch was researched.Then a triggering system was designed with a transformer driver and the self-steepening switch to satisfy the requirements of the trigatron.Statistical analysis on steepening parameters of the switch was conducted under multiple driving modes to reach the optimized self-steepening mode.The optimization combination of switching polarity,working electric field,UV radiation intensity and time were determined.The switching possibility of the trigatron was obviously improved when the self-steepening segment was inserted.Meanwhile,the delay and the jitter of the trigatron decreased significantly,and its working voltage-ratio range was broadened.
