摘　　要：借助于电磁兼容中的优势效应概念 ,将高频集总传导干扰源及其传导干扰分解为天线模和传输线模 ,分析了高频集总传导干扰源在互连设备上产生的传导干扰特性 ,指出负载上的传导干扰传输线模分量比天线模分量占优势 ,因而可以用负载上的传导干扰传输线模分量近似表示负载上的传导干扰 .建立了分析互连设备高频集总传导干扰的传输线模型 .推导出了高频传导干扰负载响应的矩阵表示式 .通过实例计算 。By the aid of a concept of dominant effect in EMC, the lumped high-frequency conducted interference source and its conducted interference are decomposed into antenna mode and transmission-line mode. The transmission-line models applied to the analysis of lumped high-frequency conducted interference of some interconnecting equipment are presented. The matrix form of the load responses due to the lumped high-frequency conducted interference sources is derived. The computational results of some typical examples show that the transmission-line models are valid, compared with the reference.
