Abstract: The present invention provides regulation for an output voltage of a DC-DC voltage converter. The controlled variable provided to the regulator of the DC-DC voltage converter is in this case made up of a controlled variable from a voltage regulator and a further controlled variable from an initial controller. The controlled variable from the voltage regulator is in this case obtained directly from the comparison of the output voltage with a setpoint voltage. The controlled variable from the initial controller takes into consideration, inter alia, the input voltage of the DC-DC voltage converter, the value of the input DC voltage being able to be corrected such that the voltage regulator can be operated close to the zero point during steady-state operation. In this manner, faster and more precise regulation of the output voltage is obtained.
