A 2D finite element formulation for the study of the high frequency behaviour of wound components

When the frequency of power converters increases, their wound components, such as inductors or transformers, can no longer be supposed ideal. In this paper, a formulation using 2D finite elements is presented for studying these high frequency coupled magnetic and electric field problems (eddy currents, proximity effects and stray capacitance). This formulation is based on a particular division of the 3D spatial domain which enables a 2D calculation.
