Eddy-Current-Effect Homogenization of Windings in Harmonic-Balance Finite Element Models

The eddy-current effects in windings, i.e. skin and proximity effects, can be macroscopically modelled via a complex frequencydependent impedance and reluctivity. In this work, these two complex quantities are further embedded in a harmonic-balance finite element model for arriving at the steady-state solution. The proposed approach is validated through a 2D model of an inductor with pulse-width modulated voltage supply. Both local and global quantities are shown to agree well with brute-force simulation results. The computational cost of both approaches is compared.status: publishe
