This paper presents an application of an adapted (R-L-M-C) PEEC method dedicated to the extraction of equivalent circuit of power electronics devices. Two dedicated integral methods with different meshes are used to compute either resistive and inductive elements or capacitive couplings. The adaptive multi-level fast multipole method (AMLFMM) is presented to extract parasitic capacitances on large geometries. By coupling these two methods, an equivalent circuit with lumped elements is obtained. Consequently, EMC simulations on a wide frequency range are feasible by means of a SPICE-like tool. These methods have been applied to a boost converter.
