Design, modeling and analysis of a new dual input-output switched capacitor converter

Abstract

A new dual-input and dual-output switched capacitor (SC) converter is designed to operate with two independent voltage sources that provides two different output voltages. The only converter generates 32 voltage conversion ratios (VCRs). The converter is portable to operate with one or two input sources alternatively and having the ability to vary 32 voltage ratios. An efficient low power SC converter is designed for input voltage of 1.5 V to 5 V that gives dual output voltages of 1 V to 10 V. The designed converter can operate in both buck and boost modes. This SC converter has high drive capability of load current from 10 μA to 25 mA that is adjusted by operating frequency. Modeling, analysis are performed to verify the dual output converter mathematically and also verified using PSIM simulations. The mathematical results and simulation results show excellent proof of newly designed converter. © 2017 IEEE.
