Title: TWO-PHASE, THREE-PHASE RECONFIGURABLE SWITCHED-CAPACITOR POWER CONVERTER
Abstract:
The technology described herein is generally directed towards a reconfigurable switched-capacitor power converter that operates in multiple switching modes, including one or more implementations having a two-phase switching mode driven by a two-phase clock, and a three-phase switching mode driven by a three-phase clock. Various configurations of logic-controlled switches, corresponding to specified voltage conversion ratios, are achieved by driving certain switches according to the two-phase clock in the two-phase mode and the three-phase clock in the three-phase mode. For example, by using two flying capacitors and controlling ten switches to provide different configurations of alternating circuits, six different non-zero voltage conversion ratios are realizable.
