Abstract :
This paper shows that a switched-capacitor DC-DC converter can be designed to process up to several tens of watts of output power at an efficiency exceeding 80%. Converter operation is analyzed by “modified state-space-averaging”, which is generally suitable for analysis of converters with nonlinear ripple. A design procedure is presented along with experimental verification
