VEHICLE CHARGING CIRCUIT AND VEHICLE ELECTRICAL SYSTEM HAVING THE VEHICLE CHARGING CIRCUIT

A vehicle charging circuit includes an AC voltage connection that has a plurality of potentials, a switch device, a plurality of rectifiers that are each in the form of a bridge rectifier, a plurality of step-up converters, and a plurality of galvanically isolating DC-DC converters. Inputs of the rectifiers are connected to one other. The interconnected inputs of the rectifiers are connected to the AC voltage connection via the switch device. The rectifiers each have an output, downstream of each of which is connected one of the step-up converters. The step-up converters are connected to a rechargeable battery connection of the vehicle charging circuit.
