Abstract:
A multi-level converter includes a flying capacitor and a resistive voltage divider. The multi-level converter is configured to convert an input voltage into an output voltage. The resistive voltage divider is configured to charge a flying capacitor in the multi-level converter during an initial charging mode of operation. In some implementations, the multi-level converter includes a plurality of flying capacitors and a plurality of resistive voltage dividers including a resistive voltage divider for each flying capacitor in the plurality of flying capacitors.
