Abstract:
1. An apparatus configured for energy transfer from an input to an output, the apparatus comprising: at least a first capacitor, a second capacitor, and a third capacitor, wherein the third capacitor is coupled to the output; and a first plurality of switches including a first switch, a second switch, a third switch, a fourth switch, and a fifth switch; and a processing module configured to control the plurality of switches; wherein a first terminal of the first capacitor is coupled to a first terminal of the third capacitor through the first switch, a second terminal of the first capacitor is coupled to a second terminal of the third capacitor through the second switch, a first terminal of the second capacitor is coupled to the first terminal of the third capacitor through the third switch, a second terminal of the second capacitor is coupled to the second terminal of the third capacitor through the fourth switch, and the second terminal of the first capacitor is coupled to the first terminal of the second capacitor through the fifth switch; and further wherein the processing module is configured to, on a condition that an amplitude of a voltage at the input is low in comparison to a voltage at the output, control the first plurality of switches to charge the third capacitor directly from the input without first charging the first capacitor and the second capacitor.
