摘要
为了雷电间接效应测试需要,提出一种能量效率较高的冲击电流发生器电路拓扑。该拓扑可以产生缩比雷电流H波。从串联RLC回路出发,运用Multisim仿真设计软件,着重研究回路参数对于冲击电流波形的影响程度,总结了电流峰值、波前时间和半峰值时间与电路参数的关系表。设计了满足标准要求的H波电流发生器电路,实际测试结果显示波形与仿真分析相吻合。该高效电流发生器拓扑可以为一般非振荡的指数波发生器设计提供借鉴。
In order to test the indirect effect of lightning,a topology of impulse current generator with high energy efficiency is proposed.The topology can generate a reduced lightning current witch is H wave.From the RLC series circuit,using the Multisim simulation software,the influence of circuit parameters on the impulse current waveform is studied,and the relationship between the current peak value,wavefront time and half peak time and circuit parameters is summarized.The circuit of H wave current generator which meets the standard requirement is designed.The actual test results show that the waveform is in agreement with the simulation analysis.The topology of the high-efficiency current generator can be used for reference in the design of general non-oscillating exponential wave generator.
