Abstract :
A simplified model which takes into account minimum coupling paths (MCP) for a switching mode power converter is presented. A minimum number of coupling capacitors are found which connect between all three terminals of a LISN and nodes of a converter circuit. Simulation that shows both inductive and capacitive coupling mechanisms may contribute substantial noise at the input
