In a single-ended forward converter with a transformer (Tr) and a storage capacitor (C1), in which the storage capacitor (C1) together with an inductor (L1) forms a main resonant circuit (L1, C1), an RC series circuit (C3, R1) is connected directly to the transformer (Tr) as a demagnetising device. The capacitor (C3) of the RC series circuit (R1, C3) is dimensioned such that the further resonant circuit, which is formed by the capacitance of the further capacitor (C3) with the cross-inductance of the transformer (Tr), corresponds at least approximately to that of the main resonant circuit (L1, C1).
