Abstract
(EN)
The invention relates to a transformer (21). In order to limit the height of the transformer (21), it comprises a planar primary winding (30) and a plurality of planar secondary windings (33). Each secondary winding (33) provides an isolated output (34, 35). The secondary windings (33) are arranged side by side in a plane parallel to the primary winding (30) such that a portion of a magnetic flux generated by the primary winding (30) penetrates each of the secondary windings (33). The invention relates equally to an apparatus (10, 15) comprising such a transformer (21) and to a method of producing such a transformer (21).

L'invention concerne un transformateur (21). Ce transformateur (21) comprend un premier enroulement primaire plane (30) et une pluralité d'enroulements secondaires planes (33) qui permettent de limiter sa hauteur. Chaque enroulement secondaire (33) fournit une sortie isolée (34, 35). Les enroulements secondaires (33) sont agencés côte à côte dans un plan parallèle à l'enroulement primaire (30) de sorte qu'une partie d'un flux magnétique généré par l'enroulement primaire (30) pénètre dans chaque enroulement secondaire (33). L'invention concerne également un appareil (10, 15) comprenant un tel transformateur (21) et un procédé de production d'un tel transformateur (21).
