【Abstract】 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.更多还原
