Abstract

La présente invention vise un composant magnétique comprenant deux demi-noyaux ferromagnétiques empilés et superposés pour former un cœur ferromagnétique comprenant trois jambes (11, 12, 13) dont deux premières jambes (11, 13) et une deuxième jambe (12), chaque jambe (11, 12, 13) étant formée de deux demi-jambes en vis-à-vis et séparées par un entrefer, chaque jambe (11, 12, 13) comprenant un enroulement primaire (111, 121, 131) et un enroulement secondaire (112, 122, 132) présentant un sens d’enroulement, respectivement sur chacune des demi-jambes qui la constituent, le composant magnétique étant caractérisé en ce que, sur la deuxième jambe (12), l’enroulement primaire (121) et l’enroulement secondaire (122) ainsi que leur sens d’enroulement sont inversés par rapport à ceux (111, 112, 131, 132) des premières jambes (11, 13).
