Modified SEPIC DC-to-DC boost converter with high output-gain configuration for renewable applications

Abstract

This paper articulates the novel topology for modified SEPIC converter and much suitable for renewable energy and high-voltage applications. Power circuit incorporated with one additional inductor and capacitor to the classical SEPIC converter as a voltage lift component. Hence, it overcomes the effect of parasitic effects of the circuit components (MOSFET/passive elements). Conventional DC-DC boost/SEPIC converters are utilized for renewable energy and industrial applications. But they suffer from parasitic effects with reduced output voltage, and limited with low efficiency. Henceforth, these difficulties overcomes with the modified SEPIC converter topology for maximizing the output voltage generation. Numerical simulation outcomes are presented and validate the developed theoretical analysis and the accuracy of modified circuit. © 2017 IEEE.
