Abstract :
A simplified physical model of a switch mode power converter concludes a minimum of six equivalent physical coupling paths, least coupling paths (LCP), using lump elements approach through noncontact EMI coupling mechanism to the terminals of LISN. Simulation shows both inductive and capacitive coupling through each path may produce substantial EMI measured by a LISN. This physical model is good for understanding, diagnosis and emission estimation
