Abstract

In this paper, dual input step-up switched capacitor inductor (SCI) converters have been investigated. At first, the structure of this converter was reviewed and analyzed carefully. It is showed that besides capacitor and inductor, a small resonant inductor is also used in order to limit the current peak caused by switched capacitor. Therefore, efficiency has been improved. Fuzzy control method used for switching control of the circuit and simulation results showed that, output waveforms are according to idealized ones, output voltage ripple decreased dramatically and high voltage gained has been achieved
