摘　　要：火花隙开关的触发导通需要一个幅值高,上升速度快,与其他电路高度隔离的脉冲触发信号。首先通过PSpice仿真的方法对一种高压脉冲电源的方案进行了验证,并根据仿真结果选择了合理的电路参数,然后试制了高压脉冲电源,并对之进行了测试。结果表明,通过仿真分析的方法能够验证设计方案,简化和缩短研发过程,该高隔离度的高压脉冲电源能够提供25 kV以上的隔离强度,输出幅值为15 kV以上的负脉冲,满足触发火花隙开关的需求。Triggering spark gap switches requires trigger signals with high amplitude, fast rising time, and to be highly isolated from other circuits. After verifying a scheme of high-voltage power supply by means of PSpice simulation, we developed and tested a pulsed power supply with parameters selected according to the simulation results. The results show that the simulative method above is capable of verifying design schemes of power supplies, as well as simplifying and shortening the development process. The proposed pulsed power supply has isolating strength over 25 kV and can gener- ate negative pulses with amplitude over 15 kV, which meets the demand of triggering spark gap switches.
