A family of single-stage-switched-capacitor-inductor converters with different voltage conversion features and similar structures is presented in this paper. Unlike conventional switched-capacitor/switched-inductor converters that are produced by cascade operation, all of the proposed converters are operated in single-stage mode. Though each of the proposed converters employs two energy transfer components, i.e., one switched capacitor and one inductor, energy flowing though the two components both directly come from the input power sources and then is directly released to output terminal. This design can meet the high efficiency requirement and simple structure. A small resonant inductor is also used in these converters to limit the current peak caused by switched capacitors and to improve efficiency. The detailed analysis of circuit operation and design consideration is given. Simulation and experimental results are also provided to verify the performance of the new family of converters.
