摘要
Structures and methods are provided for attaining high step-up and high step-down DC-to-DC power conversion using switched-capacitors. The DC-DC converters are comprised of a modular configuration of capacitors and switches and attain step-up ideal conversion ratios greater than 2N and step-down ideal conversion ratios less than 1/2N, where N is the number of floating capacitors used by the converter. A method is provided for controlling the converters, wherein the control circuit generates a multiphase switching sequence which opens and closes the switches such that the converter cycles through a plurality of topological states. Sample switching sequences are provided to generate a set of attainable ideal conversion ratios for embodiments of the converters using three and four floating capacitors.
