Abstract
A switched-mode power supply for supplying an operating voltage to a frequency converter includes a supply capacitor configured to supply the operating voltage to a control device for generating control signals for semiconductor switches of the switched-mode power supply. The supply capacitor is chargeable through a start-up circuit from a DC link of the frequency converter. The start-up circuit includes a current regulator that is configured to control a total current from the DC link to the start-up circuit.
