摘　　要：为了满足多路精确同步触发开关要求,将光导开关(PCSS)与V/N气体开关结合,可充分发挥PCSS低触发阈值、低抖动和光电隔离以及V/N气体开关工作电压高、带载能力强等优势。两种开关结合的核心是V/N气体开关结构参数与PCSS触发回路的参数匹配。分析计算了V/N气体开关的结构电容、触发回路振荡参数、开关电场分布等,研究了V/N气体开关的结构电容与PCSS、串联电感等构成的振荡回路的匹配关系,通过实验获得了V/N气体开关自击穿电压曲线、导通延迟时间以及不同欠压比下的延迟时间抖动等,初步验证了适用于PCSS触发的V/N气体开关设计。To meet the requirements of multi-channel precise synchronous trigger switch,photo conductive semiconductor switch(PCSS)is combined with V/N gas switch,which takes advantage of the photoelectric isolation,low trigger threshold,low delay time jitter and photoelectric isolation of PCSS,as well as the advantages of high operating voltage and strong load capacity of V/N gas switch.The core of the combination of the two switches is that the structural parameters of the V/N gas switch match the parameters of the PCSS trigger loop.The structural capacitance,trigger loop oscillation parameters and switching electric field distribution of the V/N gas switch are analyzed and calculated.The relationship between the structural capacitance of the V/N gas switch and the oscillation loop composed of PCSS and series inductors is studied.The self-breakdown voltage curve,on-delay time and delay time jitter of the switch under different under voltage ratios are obtained.The performance of the V/N gas switch for PCSS triggering is preliminarily verified.
