The design of efficient switched capacitor power converters is addressed. It starts with a review of the fundamental limitation of switched capacitor circuits which shows that the topology of such circuits and the forced step changes of capacitor voltages are inherent attributes of power loss. Also discussed is a simple version of lossless topology that achieves isolation between the source and the load. An experimental AC/DC switched capacitor converters based on an improved efficiency over other existing switched capacitor converters is presented. The proposed AC/DC converter contains no inductors and is suitable for custom IC implementation for very low power applications.
