Abstract

L'inducteur selon l'invention comprend : un noyau présentant au moins un premier trou traversant et un second trou traversant pénétrant dans la même direction ; un premier conducteur à travers lequel passe un premier courant, le premier conducteur présentant une partie insérée à travers le premier trou traversant ; et un second conducteur à travers lequel passe un second courant, le second conducteur présentant une partie insérée à travers le second trou traversant. Un courant parmi le premier courant et le second courant est un courant par lequel l'autre courant revient à l'inducteur après avoir traversé l'extérieur de l'inducteur. La direction du second courant dans le second trou traversant est opposée à la direction du premier courant dans le premier trou traversant.
