Homogenization of materials used in all-film metallized capacitors
Résumé
The structure of metallized capacitors is complex and the sizes of the constituting elements are dissimilar. Consequently, direct computation of fields and current densities is impossible. In this paper, we give some macroscopic properties (impedances, admittances) of the capacitor winding, obtained thanks to an homogenization method. These properties are helpful to compute the current and heating distribution in capacitors.
