Abstract
A power converter-circuit () having a transformer (T), comprising a snubber-circuit (C, D, S, D) for suppressing voltage peaks on a secondary side of the transformer (T) that comprises a snubber capacitor (C); and an auxiliary DC-DC converter () having a first input connected with the snubber capacitor (C) and a first output connected with a first output (V) of the power converter-circuit (). This circuit increases efficiency of electrical conversion and reduces thermal losses.
