摘要: 利用脉冲高压陶瓷电容器和高气压小间隙开关，研制了60 kV同轴式高压快沿脉冲源。利用自行研制的薄膜式电容分压器和同轴式电阻分压器对快沿脉冲源的输出参数进行测量，分析了薄膜式电容分压器的测试原理，对电容分压中二级电阻分压器元件的参数进行了优化。当脉冲源负载为50 W时，测得脉冲源输出电压的前沿小于2.3 ns，半高宽约28 ns，符合IEC电磁脉冲的最新标准。Abstract: Based on ceramic pulse capacitors and high press gas switch, a 60 kV coaxial fast rising pulse source was developed. A foil capacitive divider and a resistive divider were developed for measuring the output voltage of the fast rising pulse source. The test result indicats that the rising time of the output voltage of the pulse source is less than 2.3 ns and the pulse width is about 28 ns with a 50 W dummy load. This result agrees with the newest EMP standard of IEC.
