Design of series, Fi=Fi-1+Fi-3 for the denominators (1, 2,6) of switched capacitor converter

Abstract

This paper proposes, the concept of generalized Fibonacci switched capacitor converter for F<inf>i</inf>=F<inf>i-1</inf>+F<inf>i-3</inf> series. The proposed converter have more efficiency and less equivalent resistance. Generalized Fibonacci switched capacitor converters (SCCs) are technologically advanced which operates on fixed conversion ratio. Different target ratios of Fibonacci series have already been carried out by the researchers to step-up and stepdown configuration. But, different target ratios of F<inf>i</inf>=F<inf>i-1</inf>+F<inf>i-3</inf> series has not yet proposed. In this paper different fractions 1/4,3/4,1/6,5/6 for SCC is proposed for both step-up and stepdown configurations. Theoretical results and simulation results are verified using PSIM. © 2016 IEEE.
