Title
(EN) ELECTROMAGNETIC ASSEMBLY FOR A RESONANT CONVERTER
(FR) ENSEMBLE ÉLECTROMAGNÉTIQUE POUR CONVERTISSEUR RÉSONANT
Abstract
(EN)
The invention relates to an electromagnetic assembly for an LLC-type resonant converter, comprising: a first compartment housing a single-phase transformer, the secondary winding of which is wound around a first magnetic core (N1) and the primary winding of which is wound around the secondary winding, a second compartment housing the series inductor of the converter, the series inductor being wound around a second magnetic core (N2), the winding of the series inductor having a first winding wound around the second magnetic core and electrically connected to a terminal of the primary winding, the other terminal of the primary winding being electrically connected to a second winding of the series inductor, the second winding being wound around the first winding.
