摘    要: 研究了300 kV脉冲电压作用下自耦式紫外预电离开关的工作原理。为了在脉冲电压下实现开关的自耦合预电离,设计了适当的分压电路及预电离结构。模拟计算表明,分压电路参数合适时,可以实现预电离间隙与开关主间隙的击穿配合。实验结果表明:在脉冲电压作用下,调节电路参数可以有效调节紫外预电离产生时刻;在适当的时刻产生紫外预电离可以有效减小开关击穿抖动;该开关在240 ns上升时间脉冲电压作用下击穿抖动可小于3 ns,在36 ns上升时间脉冲电压作用下击穿抖动可小于2 ns。

关 键 词:脉冲气体开关  紫外预电离  抖动  脉冲功率技术

Abstract:A capacitance-resistance coupling UV illumination switch under 300 kV breakdown pulse voltage was designed and studied. The UV illumination structure and circuit parameter are important to the design of the switch. The simulation results indicated that the breakdown matching between UV gap and switch could be achieved with an appropriate capacitance-resistance coupling circuit. Experimental results indicated that the UV illumination time was adjusted effectively when resistance was changed within a certain range. Accordingly, the jitter of the UV illumination switch was decreased by adapting the UV illumination time for the pulse voltage. The jitter of the UV illumination switch was less than 3 ns under pulse voltage with 240 ns risetime , and less than 2 ns under pulse voltage with 36 ns
Keywords:UV illumination  Jitter  Pulsed power technology
