Abstract:
1. A power converter circuit comprising: a reconfigurable switched capacitor transformation stage having a transformation stage input port and a transformation stage output port, said reconfigurable switched capacitor transformation stage comprising one or more switches and one or more capacitors configured to accept an input voltage at the input port of said reconfigurable switched capacitor transformation stage and to provide an intermediate voltage at the output port of said reconfigurable switched capacitor transformation stage and wherein said reconfigurable switched capacitor transformation stage provides power conversion at multiple distinct conversion ratios as a function of at least one of: the input voltage, the intermediate voltage, and a reference voltage; and a switching converter regulation stage having a regulation stage input port coupled to the transformation stage output port and a regulation stage output port, said switching converter regulation stage configured to accept the intermediate voltage provided by said reconfigurable switched capacitor transformation stage and configured to provide an output voltage of the power converter circuit at the regulation stage output port.
