Abstract
The switched-mode power supply contains a transformer, a switching transistor in series with the primary winding of the transformer, and a damping network on the secondary side, which has a connection for a further secondary winding via which energy is transferred from this damping network, by way of example, to a charge-storage capacitor which is coupled to this secondary winding. The connection is advantageously produced via a rectifying element, for example a diode, which is coupled after the rectifying diode (D) for the second secondary winding. In a further exemplary embodiment, the diode in the series circuit, which is connected in parallel with the rectifier diode for the first secondary winding, is not coupled to the charge-storage capacitor for the first secondary winding, but is likewise coupled to the charge-storage capacitor for the second secondary winding.
