DC FAST CHARGING STATION FOR ELECTRIC VEHICLES

Abstract:

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.
