Various embodiments of the teachings herein include a vehicle-side charging apparatus comprising: an AC voltage connection; a rectifier connected to the AC voltage connection; a first DC/DC converter and a second DC/DC converter; and a DC voltage connection. Each DC/DC converter includes a intermediate circuit capacitor and a switch unit. The rectifier is connected to the DC voltage connection via the DC/DC converters. There is a switch connecting the DC/DC converters in a switchable manner. In a first switching state the respective intermediate circuit capacitors and the respective switch units of the DC/DC converters are connected in parallel with one another and in a second switching state in series with one another. There is a third DC/DC converter connecting the rectifier to the DC voltage connection.
