An AC/DC converter includes a resonance converter (A3) which is suitable, for example, for operation with different AC line voltages from different AC power grids. The AC/DC converter further includes a bridge circuit (A4) drivable as a full-bridge circuit and as a half-bridge circuit, an arrangement (A2) working as an up-converter coupled, at least via a capacitor, (C2) to the resonance converter (A3), and a transformer (T) in the resonance converter (A3) and realizing a point (7) at which the arrangement (A2) is capacitively (C2) coupled to the resonance converter (A3). The primary winding of the transformer (T) is divided and this dividing point is arranged as the point (7).
