Abstract :
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
