The invention relates to a device for generating DC voltage from AC voltage with parallel connected diode bridges (8) which are fed via at least one transformer, the primary windings (1, 2) of which are connected in series. The DC voltage is used for supplying DC paths, and secondary voltages on the secondary windings (5, 6) of the transformer have different phase angles. This is achieved, e.g., by the fact that one secondary winding (5) is connected in a delta configuration, and another secondary winding (6)is connected in a star configuration.
L'invention concerne un dispositif pour la génération d'une tension continue à partir d'une tension alternative avec des ponts de diode (8) montés en parallèle, lesquels sont alimentés par l'intermédiaire d'au moins un transformateur, dont les enroulements primaires (1, 2) sont montés en série. On prévoit que la tension continue sert à alimenter des trajets du courant continu, et que des tensions secondaires aux enroulements secondaires (5, 6) du transformateur présentent des rotations de phase différentes. Cela est par exemple obtenu en ce qu'un enroulement secondaire (5) est monté en triangle et en ce qu'un autre enroulement secondaire (6) est monté en étoile.
