Abstract
A method for providing two mutually different electrical DC voltages, wherein a first of the two DC voltages, which has a greater voltage value than a second of the two DC voltages, is provided by means of a clocked energy converter by using a converter switching unit of the energy converter to apply electrical energy from an electrical energy source to a storage inductor of the energy converter and to supply an electric current of the storage inductor to a first electrical capacitor at which the first DC voltage is provided. The operation of the converter switching unit is controlled depending on a result of a first comparison of the first DC voltage with a first voltage comparison value.
