| 摘 要： | 建立了包含开关放电分散性的电路模型,模型通过电压控制开关和自击穿开关模型的结合,可对开关抖动及支路间放电的相互影响进行模拟,利用研制的300kA单级直线型变压器驱动源(FLTD)模块进行了实验验证,模拟结果与实验相吻合。进而针对设计的20支路FLTD模块建立了电路模型,模拟分析了模块支路开关放电分散性对输出电流峰值和上升沿的影响,模拟结果表明,开关抖动小于5ns时对模块输出影响较小。

| Abstract: | This paper builds up a circuit model of the switch synchronously discharge in the FLTD stage and a circuit simulation model of the FLTD stage. The switch in FLTD simulation model integrates the switch controlled by voltage and self-break switch. The FLTD stage simulation model can simulate stage output influence by switch discharge jitter and bricks discharge each other. The simulation model has been validated by the experiment result of a 14-brick FLTD stage. The influence of the 20-brick FLTD stage output current peak and rise-time with switches discharge synchronously have been simulated by the circuit simulation model of the FLTD. The simulation results indicate that the stage output influence is insignificant when the jitter of switch is less than 5 ns. |
