Equivalent source correspending to radiated field of EMC filter components

摘要

EMC Filters are increasingly integrated into power applications. To improve their performances it is important to model the electromagnetic interference between components to optimize their positions in the filter. In this paper, a method is proposed to construct the equivalent models of the component radiated field. The method proposed is based on the multipolar expansion, which provides us reduced models for the field radiated by generic structures. These models of the sources will be used to compute the mutual inductance between the components according to their geometrical placement.
