Abstract
The present document relates to power transformers for electronic computing devices. In particular, a power converter configured to convert electrical power at a DC input voltage Vin into electrical power at a DC output voltage is described. The power converter comprises a plurality of flying capacitors, and a plurality of switches which are configured to arrange the plurality of flying capacitors in accordance to a sequence of operation phases. The power converter comprises a control unit configured to control the plurality of switches to repeat the sequence of operation phases at a duty cycle frequency. The plurality of flying capacitors is arranged in series during the operation phases of the sequence of operation phases. The sequence of operation phases comprises at least two operation phases during which the plurality of flying capacitors is arranged in a different order.
