Low source current-ripple high gain boost converter

Abstract

This paper presents analysis and design of low source current ripple high-gain boost converter. The proposed converter exhibits higher voltage gain, almost double, in comparison to the well-established conventional boost converter. A steady-state analysis is made, and then converter elements design expressions are established. These design expressions are then used to design a 24 to 100 V, 50 W prototype. Steady-state performance proposed converter is compared with other highgain dc-dc converters. Simulation and experimental results are presented to validate the proposed design. Experimental measurements are in close correlation to simulation results. Index Terms-Boost converter, High voltage gain, Higherorder boost converter, Quadratic Boost Converter.
