Abstract
L'invention concerne un transformateur planaire (1) comportant : - un noyau magnétique (10), - un bobinage primaire (20) et un bobinage secondaire (30) entourant au moins une partie (101) du noyau magnétique, et - un circuit imprimé (40) comprenant au moins une couche de matériau électriquement isolant et au moins une piste électriquement conductrice, dans lequel l'un du bobinage primaire et du bobinage secondaire comprend au moins une spire formée dans la piste conductrice du circuit imprimé, caractérisé en ce que le circuit imprimé comporte un renfoncement (43) agencé à la surface de la couche de matériau isolant et présentant une profondeur inférieure à l'épaisseur de ladite couche de matériau isolant, et l'autre bobinage comprend une spire (50), formée dans une feuille de matériau conducteur, reçue au moins partiellement dans ledit renfoncement (53).
