Abstract: A DC/DC power supply with two transformers (10, 20), which for example are connected in parallel on the primary and in series on the secondary side, comprises two passive, non-dissipative snubber circuits (1.1, 1.2). Each snubber circuit comprises a series circuit formed by a capacitor (3.1, 3.2) and a diode (4.4, 4.7), which is connected to the output capacitor (13) of the power supply. The transformers are interleaved with a push-pull configuration. On the secondary side, the power supply has an output choke (12, 22) and two output rectifiers (11, 21) are connected to the secondary winding (14, 24) of each transformer. Each snubber circuit further comprises two additional diodes (4.5, 4.6, 4.8, 4.9), one electrode of these diodes being connected to the joint electrode of the snubber capacitor (3.1, 3.2) and the first snubber diode (4.4, 4.7) and the other electrodes being connected respectively to an end of the secondary winding (14, 24) of a transformer.
