A circuit arrangement for generating an auxiliary DC voltage is disclosed. The circuit arrangement includes a half bridge circuit outputting a load current, which half bridge circuit converts a DC voltage to an AC voltage, and at least two intermediate circuit capacitors arranged on the input side, in series parallel to the half bridge circuit. The circuit arrangement further includes an auxiliary voltage generating unit supplied with electrical energy by one of the intermediate circuit capacitors, and which is configured to generate an auxiliary DC voltage of less than or equal to 48V. The disclosure 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.
