摘要: 报导了一种高压串级延迟击穿（DBD）开关在快脉冲触发源中的应用，介绍了脉冲源的电路结构和工作原理，并将DBD开关成功应用于快前沿脉冲触发源，获得了明显的脉冲陡化效果。串级DBD开关的级数为15级，直流击穿电压45 kV，脉冲工作电压60 kV，脉冲前沿由95 ns减小到21.5 ns，脉冲宽度50 ns。

Abstract: High power delayed breakdown device(DBD) switches containing fifteen seriesconnected semiconductor structures are introduced. The seriesconnected DBD switches have been applied to fast risetime trigger generator. The experimental results show that the input pulse is sharpened significantly by seriesconnected DBD switches.The seriesconnected DBD switches have a holdoff voltage 60 kV, and the risetime is reduced from 95 ns to 21.5 ns.The pulse width of output pulse is 50 ns．
