A voltage converter (1a . . . 1g), in particular a resonant converter for converting an input AC or DC voltage (UE) into an output DC voltage (UA). On the secondary side, a first secondary capacitor (CS1) is arranged between the secondary partial windings (WS1, WS2) of a transformer (TR1); furthermore, a first secondary full-bridge rectifier (GS1) provides the output direct voltage (UA), the inputs of which are connected to a secondary partial winding (WS1, WS2) each of the transformer (TR1), resulting, at the input of the first secondary full-bridge rectifier (GS1), in a series connection including the secondary partial windings (WS1, WS2) and the first secondary capacitor (CS1). Finally, the voltage converter (1a . . . 1f) includes a second secondary full-bridge rectifier (GS2) connected in parallel with the first secondary full-bridge rectifier (GS1) for providing the output direct voltage (UA), wherein the first secondary capacitor (CS1) is connected to the input of the second secondary full-bridge rectifier (GS2).
