【摘要】 对大功率延迟触发器中使用的氢闸流管的栅极点火特性,特别是延迟时间分散度做了比较细致的研究,对延迟时间做了理论计算,理论和实验符合得很好。本实验所用的延迟触发器输出电压幅度为3kV,电阻性负载的输出功率为十分之几兆瓦,最大时延50μs,改进型RC延迟器的时间分散度小于70ns,LC延迟触发器的时间分散度小于20ns。最后对进一步提高延迟时间的稳定性提出了若干改进措施。更多还原

【Abstract】 The performance of a high power trigger is described. Much attention has been paid to the jitter of delay time. Both the delay time and its jitter have been calculated in good agreement with experimental results. The Output voltage of the delayed trigger reaches 3kV with power of a few tenths of megawatt. Maximum delay time obtainable is about 50μs with time jitters less than 70ns and 20ns for RC delayed trigger and LC delayed trigger, respectively. Several methods are proposed to reduce the jitter of delay time.更多还原
