The invention relates to a converter comprising a full-bridge circuit comprising a first, second, third and fourth switching element (S1, S2, S3, S4), for converting a DC voltage (UBat) into an AC voltage (U~); a circuit (3) comprising at least a capacitive element (Cs) for coupling the full-bridge circuit to a converter output; a control circuit (5) for controlling the switching elements (S1, S2, S3, S4) of the full-bridge circuit, a first mode being provided in which the full-bridge circuit is operated as a half-bridge circuit by a change of the switching states of the first and second switching elements (S1, S2) and the switching states of the third and fourth switching elements (S3, S4) are not changed, and a second mode being provided in which the full-bridge circuit is operated as a full-bridge circuit by a change of the switching states of all four switching elements (S1, S2, S3, S4). Such a converter is suitable for use with different mains voltages of different AC voltage networks.
