A general method for coupling electronic circuits with 3D electromagnetic fields

摘要

An effective scheme allowing strong coupling of electronic circuits with three-dimensional electromagnetic fields is presented in this paper. The electromagnetic field is represented by means of an edge element method. The state-space formulation is employed to describe the time variable topology of the electronic circuit. The whole system is solved with a time step procedure. The methodology is verified by comparing calculated and experimental results on a quasi-resonant power converter.
