Abstract :

[en] This paper deals with the time-domain homogenization of multiturn windings in 3-D finite element (FE) models. An elementary two-dimensional (2-D) FE model allows for the global eddy-current characterization of the winding by means of dimensionless frequency and time-domain coefficients regarding skin and proximity effects. These coefficients are used in the FE model of the complete device. The 3-D homogenization method is validated by considering an axisymmetric 120-turn inductor for which a brute-force 2-D FE model (each turn is finely discretized) provides an accurate reference solution.
