Abstract :
Switched capacitor DC/DC converters are new prototype of DC/DC Conversion technology. Since switched capacitor can be integrated into a power IC chip, consequently, these converters have small size and high power density. Switched capacitor can be used in voltage-lift technique to construct DC/DC converters. The clue is that for the converters operating in discontinuous input current mode (DICM) the switched capacitors can be charged during the input current discontinuous period. The switched capacitors are charged to the source voltage during the switch-off period. They will join the conversion operation during switch-on period, and the stored energy in them will be delivered through further elements to the load. These converters are called switched-capacitorized DC/DC converters. Simulation and experimental results are provided for verification of this design.
