摘　　要：针对雷电间接效应多重脉冲组电流模拟需求,完成了雷电间接效应多重脉冲组模拟源的设计,采用20个Crowbar电路支路,通过分时放电的方式实现1个脉冲串内多脉冲输出需求,每个支路可以实现最小间隔30 ms的重复频率放电,从而实现3个脉冲串的输出需求。对放电支路的参数进行了详细设计,分析了电容、波尾电路电感、波尾电路电阻参数变化对输出特性的影响。分析了采用并联大电容实现放电电容重复频率快速充电的可行性,完成了装置的初步结构设计并结合装置结构简要分析了电路模拟参数设置的合理性。该装置建成后,可为电子、电气设备等开展测试提供技术支持。To meet the requirements of lightning electromagnetic pulse adaptability test of electronic andelectrical equipment,it is necessary to develop a simulation device that meets the waveform of multiple pulse groupsof lightning indirect effects.Multiple pulse groups with indirect lightning effects require the output of 60 adjustableinterval current pulses,with a pulse current greater than 10 kA,a current front(10%−90%)of 100 ns,and a minimumcurrent pulse time interval of only 50μs.High requirements have been placed on analog devices.This article focuseson the simulation requirements of multiple pulse group currents for indirect effects of lightning,and has completed thedesign of a multiple pulse group simulation source for indirect effects of lightning.After the device is built,it canprovide technical support for testing electronic and electrical equipment.
