1. A vehicle-side charging circuit, comprising:
an AC voltage interface;
a rectifier connected to said AC voltage interface;
first and second DC/DC converters, said DC/DC converters being DC-isolating and each having at least one intermediate circuit capacitor and at least one switch unit;
a vehicle electrical system connection connected to said rectifier via said DC/DC converters; and
a switch apparatus configured to selectively connect said first and second DC/DC converters to one another, said switch apparatus being configured to connect said intermediate circuit capacitors and said switch units of said DC/DC converters in parallel with one another in a first switching state and to connect said intermediate circuit capacitors and said switch units in series with one another in a second switching state.
