The windings of planar magnetic components such as inductors and transformers are the seat of physical phenomena (skin effects, proximity effects and the magnetic field produced by the component) leading to a non-uniform distribution of current in the conductors and an increase in Joule losses. The objective of this paper is to identify the physical phenomena at the origin of this non-uniformity of the current in the conductors. This work is conducted using a 3D finite element software. It highlights the predominant influence of the Hz component of the magnetic field produced by the component, perpendicular to the plane of the component.
Author Keywords: Magnetic component, integrated planar devices, non-uniform current density, skin proximity and magnetic effects.

Abstract: (french)
Les enroulements des composants planaires magnétiques comme les inductances et les transformateurs sont le siège de phénomènes physiques (effets de peau, de proximité et du champ magnétique produit par le composant) conduisant à une répartition non-uniforme du courant dans les conducteurs et une augmentation des pertes Joule. L’objectif de cet article est d’identifier les phénomènes physiques à l’origine de cette non-uniformité des courants dans les conducteurs. Ce travail est conduit à l’aide d’un logiciel d’éléments finis 3D. Il met en évidence l’influence prépondérante de la composante Hz du champ magnétique produit par le composant, perpendiculaire au plan du composant.
Author Keywords: Composant magnétique, composants planaires intégrés, densité de courant non-uniforme, effets de peau, proximité et magnétiques.
