Abstract

A power converter comprising an inductor for receiving energy from a power supply, and connected to the inductor an output capacitor for providing an output voltage. In order to ensure a quick compensation of a reduction of load at the voltage output using few output capacitors, an additional current path is arranged in parallel either to the inductor or to the capacitor, which additional current path can be opened and closed. A current flowing through the additional current path reaches basically immediately a desired value, when the additional current path is opened. Feedback means are moreover provided for opening the additional current path, when the output voltage reaches a predetermined maximum value.
