通过分析场线耦合所产生的差模电流与共模电流的差异,结合国内外的发展状况,研究了电磁场对平行双线的共模耦合模型;通过数值仿真,深入分析了共模电流随频率、位置等因素的变化规律;并进一步开展了实验研究,验证了数值结果的可靠性。本文的研究成果可为电磁兼容性工程设计提供参考。
Through analyzing the difference between transmission line mode currents and antenna-mode currents caused by field-to-line coupling,an antenna-mode coupling model related electromagnetic field to two parallel lines was introduced in present associating with the development worldwide.The antenna-mode current properties in dependence with frequency and position along lines were comprehensively investigated by numerical simulation.Moreover,in order to validate the numerical results and properties obtained here,some experiments had been implemented and experimental data shows good agreement with numerical results.The conclusion obtained in the paper can provide reference for EMC project design.
