Abstract

Sur des éléments de circuit inductifs, on sait déjà fabriquer des enroulements à partir d'éléments sous forme de fils courbés en U, cintrés sur un noyau et formant, avec des pistes conductrices dans lesquelles leurs extrémités sont soudées, des enroulements complets, ce qui peut poser des problèmes thermiques et conduire à de grandes dispersions dans les paramètres électromagnétiques. Sur un élément de circuit inductif selon l'invention, des premiers (2) et seconds (4) étriers en U sont placés de façon opposée et reliés directement les uns aux autres, de façon à entourer le noyau toroïdal (3) pour former des enroulements complets. Le groupe des premiers étriers (2) est fixé sur une platine support (1) et le groupe des seconds étriers (4) est fixé sur une platine support opposée (5).
