Abstract
An apparatus for converting a first voltage into a second voltage includes a reconfigurable switched capacitor power converter having a selectable conversion gain. The power converter has switch elements configured to electrically interconnect capacitors to one another and/or to the first or second voltage in successive states. The switch elements are configured to interconnect at least some capacitors to one another through the switch elements. A controller causes the reconfigurable switched capacitor power converter to transition between first and second operation modes. The controller minimizes electrical transients arising from transition between modes. In the first operating mode, the power converter operates with a first conversion gain. In the second operating mode, it operates with a second conversion gain.
