Abstract

La présente invention concerne un convertisseur de tension (22) à plusieurs phases pour un réseau d'alimentation électrique (18) destiné à alimenter une machine électrique (12), en particulier une machine de traction électrique (14) d'un véhicule, en énergie électrique à partir d'un système d'accumulation d'énergie électrique (16). Ce réseau d'alimentation électrique (18) comprend le convertisseur de tension (22) à plusieurs phases, un convertisseur de sortie (26) monté derrière ce convertisseur de tension (22) et un circuit intermédiaire (28) monté entre le convertisseur de tension (22) et le convertisseur de sortie (26). Le convertisseur de tension (22) à plusieurs phases comprend de son côté un circuit (30) avec plusieurs unités de convertisseur de tension (32, 34), montées en parallèle côté entrée et ayant chacune une inductance (36, 38) et deux unités de commutation à semi-conducteurs (40, 42, 44, 46), ainsi qu'avec une unité de commande (48) pour commander les unités de commutation à semi-conducteurs (40, 42, 44, 46). Selon la présente invention, l'unité de commande (48) est conçue pour commander les unités de commutation à semi-conducteurs (40, 42, 44, 46) dans un mode de décharge du circuit intermédiaire de manière qu'elles réduisent la tension de circuit intermédiaire du circuit intermédiaire (28) en moins d'une seconde pour l'amener dans le domaine des petites tensions. La présente invention concerne en outre un réseau d'alimentation électrique (18) correspondant pour alimenter une machine électrique (12), un système d'alimentation en énergie (10) ayant un réseau d'alimentation électrique (18) de ce genre et un procédé de réduction d'une tension de circuit intermédiaire d'un réseau d'alimentation électrique (18) correspondant.
