Abstract
Abstract 1. Switching power supply. 2.1. In a switching power supply, a high voltage peak occurs on the transformer (Ü) during the blocking phase, which peak endangers the switching transistor (TRP). The object of the invention is to reduce these voltage peaks using simple means. 2.2. Connected in parallel with the primary winding (1) and the secondary winding (2) of the transformer (Ü) there is in each case a network having a capacitor (CS), a diode (DS1) and a resistor (RS). 2.3. Particularly suitable for a switching power supply for a television or a video recorder. <IMAGE>
