Abstract
L'invention concerne un inducteur couplé à m phases comprenant un noyau magnétique comprenant un premier élément magnétique d'extrémité, un second élément magnétique d'extrémité et M tiges disposées entre les premier et second éléments magnétiques d'extrémité et les reliant. M représente un nombre entier supérieur à un. L'inducteur couplé comprend en outre M enroulements, chaque enroulement étant doté d'une section transversale sensiblement rectangulaire. Chacun des M enroulements est au moins partiellement enroulé autour d'une tige respective.
