二种纳秒前沿高压脉冲源的设计方案

摘要

高压脉冲源在电气电子产品的电磁兼容性测试中有着广泛的应用．本设计采用升压斩波电路与直流高压电源相结合的方法，通过3级Marx发生器产生纳秒前沿的高压电磁脉冲．仿真结果表明，本方案所设计的脉冲源，使用3kV直流电压源即可产生前沿1．8—2．8ns，幅值约88kV的双指数脉冲．%High-voltage pulse generator is widely used in the electromagnetic compatibility test of both electronic and electrical products. Combined boost circuit with high DC voltage generator,this design can produce high-voltage pulse through 3-level Marx generator. The simulation has proved that this design can generate 2ns rise time and 88KV peak voltage pulse when using 3KV DC voltage.
