Résumé :

In this paper, we propose a homogenization technique for the terminal-capacitance computation of multi-Turn windings in electrostatic finite-element methods. The approach is based on a characterization of the elementary zones where the electrical energy is concentrated. It is valid for conductors of arbitrary cross-section and packing with standard or fly-back connections and orthogonal or orthocyclic dispositions. The results of the homogenized approach present excellent agreement with those obtained by accurate but expensive finite-element models, wherein all turns and insulation layers are explicitly discretized, and by experimental validation.
