Abstract :
This paper investigates the recent developments on switched-capacitor converters for high power applications. Based on an analysis on the shape of capacitor charging current for switched-capacitor converters, technologies used to improve the efficiency and reduce the Electromagnetic Interference (EMI), including the soft-switching and interleaving scheme, are discussed. Several existing topologies for high-power switched-capacitor converters are summarized and compared with respect to components stress and efficiency. A new voltage regulation method for high-power switched-capacitor converters is also introduced.
