Zusammenfassung:	The invention relates to an AC-DC converter including an autotransformer (3) having a primary winding (5) connected in a triangle and two secondary windings (7) connected in a star, the two secondary windings being connected to a rectifier stage (4). The windings of the autotransformer are arranged in notches formed around inner teeth of a cylindrical mounting (30) in the form of a stator of an electric machine with a nested coil structure. Convertisseur alternatif/continu comportant un autotransformateur (3) ayant un enroulement primaire (5) connecté en triangle et deux enroulements secondaires (7) connectés en étoile, les deux enroulements secondaires étant connectés à un étage redresseur (4). Les enroulements de l'autotransformateur sont disposés dans des encoches formées autour de dents intérieures d'un support cylindrique (30) en forme de stator de machine électrique avec une structure de bobinage imbriquée.
