A Converter (1a.1c) for single-phase and three-phase Operation which comprises a three-phase rectifier to which three coils (La, Lb, Lc) are connected on the mains side is described. A first coil (La) is provided on the mains side with a switch (S) which connects the first coil (La) to the mains during three-phase Operation and connects it via a capacitor (C) either to the lower end (FP) of the rectifier or on the mains side to another coil (Lb, Lc) during single-phase Operation. In addition, a d.c. voltage supply and a battery charger (5a.5c) which comprise the Converter (1a.1c) according to the invention are described. Le convertisseur (1a, 1c) destiné à une utilisation monophasée et triphasée selon la présente invention comprend un redresseur triphasé sur lequel sont connectées trois bobines (La, Lb, Lc) du côté du réseau électrique. Une première bobine (La) est équipée du côté du réseau électrique d'un commutateur (S) qui connecte la première bobine (La) au réseau électrique au cours de l'utilisation triphasée et qui la connecte via un condensateur (C) soit à l'extrémité inférieure (FP) du redresseur soit du côté du réseau électrique à une autre bobine (Lb, Lc) au cours de l'utilisation monophasée. De plus, la présente invention a trait à une alimentation en tension continue et à un chargeur de pile (5a, 5c) qui comprennent le convertisseur (1a, 1c) selon l'invention.
