Title
(EN) LOW-HEIGHT COUPLED INDUCTORS
(FR) BOBINES D'INDUCTION COUPLÉES DE FAIBLE HAUTEUR
Abstract
(EN)
A coupled inductor includes a ladder magnetic core including (a) a first rail and a second rail separated from each other in a first direction and (b) a plurality of rungs separated from each other in a second direction. The second direction is orthogonal to the first direction, and each rung of the plurality of rungs is disposed between the first rail and the second rail in the first direction. The coupled inductor further includes a plurality of windings, where each winding of the plurality of windings is partially wound around a respective one of the plurality of rungs such that each winding of the plurality of windings does not overlap with itself when the coupled inductor is viewed cross-sectionally in a third direction. The third direction is orthogonal to each of the first direction and the second direction.
(FR)
Une bobine d'induction couplée comprend un noyau magnétique d'échelle comprenant (a) un premier rail et un second rail séparés l'un de l'autre dans une première direction et (b) une pluralité d'échelons séparés les uns des autres dans une seconde direction. La seconde direction est orthogonale à la première direction, et chaque échelon de la pluralité d'échelons est disposé entre le premier rail et le second rail dans la première direction. La bobine d'induction couplée comprend en outre une pluralité d'enroulements, chaque enroulement de la pluralité d'enroulements étant partiellement enroulé autour d'un échelon respectif de la pluralité d'échelons de telle sorte que chaque enroulement de la pluralité d'enroulements ne se chevauche pas lui-même lorsque la bobine d'induction couplée est vue en coupe transversale dans une troisième direction. La troisième direction est orthogonale à chacune de la première direction et de la deuxième direction.
