Abstract

L'invention se rapporte à une bobine d'inductance, qui comprend une barre (10) conductrice allongée de section transversale rectangulaire, dont au moins une partie est entourée d'un manchon (20) qui empêche sensiblement un courant électrique provenant de la barre conductrice de le traverser. Ainsi, ledit manchon (20) concentre les lignes d'induction magnétique. Une telle bobine d'inductance présente l'avantage qu'à des fréquences élevées (par exemple supérieures à 100 Hz), l'effet de peau est atténué tandis qu'à des fréquences moins élevées, mais à des courants élevés, la contrainte qu'elle subit est également atténuée.
