A Novel Non-Isolated High-Gain Boost DC- DC Converter with Single Switch and Minimum Component Count

Abstract

This paper presents a novel non-isolated unidirectional DC-DC converter aimed to achieve substantial voltage gain while minimizing component stress and maintaining a low component count. The converter's architecture amalgamates modified Single-Ended Primary Inductance Converter (SEPIC) and traditional Cuk topologies, employing only a single switch. A comprehensive analysis of the derivation, operational principles, and steady-state characteristics of this novel converter is provided. Additionally, the paper encompasses dynamic modeling of the proposed converter and elucidates the design of closed-loop controllers tailored for current control modes. Extensive analysis and simulation results substantiate the effectiveness and performance of the proposed topology. This innovative converter offers a promising solution for efficient energy transfer, delivering exceptional voltage gain suitable across various applications. © 2024 IEEE.
