Title (EN) DC FAST CHARGING STATION FOR ELECTRIC VEHICLES
(FR) STATION DE RECHARGE RAPIDE C.C. POUR VÉHICULES ÉLECTRIQUES
Abstract:
(EN) A DC charging circuit for an electric vehicle includes a neutral-point clamped (NPC) rectifier and a DC/DC buck converter. The NPC rectifier is configured to convert three-phase AC power to a first DC voltage at a rectifier output stage. The DC/DC buck converter includes a first DC stage coupled to the rectifier output stage, and a second DC stage configured to be coupled to the electric vehicle. The DC/DC buck converter is configured to convert the first DC voltage to a second DC voltage to be supplied to the electric vehicle.
(FR) Circuit de recharge charge c.c. pour un véhicule électrique, comprenant un redresseur de tension à neutre clampé (NPC) et un convertisseur abaisseur c.c./c.c.. Le redresseur NPC est conçu pour convertir une puissance alternative triphasée en une première tension continue au niveau d'un étage de sortie de redresseur. Le convertisseur abaisseur c.c./c.c. comprend un premier étage c.c. couplé à l'étage de sortie de redresseur, et un second étage c.c. conçu pour être couplé au véhicule électrique. Le convertisseur abaisseur c.c./c.c. est conçu pour convertir la première tension continue en une seconde tension continue à fournir au véhicule électrique.
