The invention relates to a circuit arrangement (1) for generating an auxiliary DC voltage (VLV), having:—a half bridge circuit (2) which outputs a load current (IL) and which converts a DC voltage (V1) into an AC voltage, and—wherein the half bridge circuit (2) has, in each of the two branches (A1, A2), at least two switch elements (S1, S2 and S3, S4) arranged in series and—wherein a flying capacitor (3) is connected in parallel to corresponding switch elements (S2, S3) in each of the two branches (A1, A2), characterized by:—an auxiliary voltage generating unit (5) which is supplied with electrical energy by the flying capacitor (3) and which is designed to generate an auxiliary DC voltage (VLV) which is less than or equal to 48 V. The invention also relates to an associated method for generating an auxiliary DC voltage and to a power converter and a vehicle having such a circuit arrangement.
