Mandal, S.Prabhakaran, P.2026-02-0620242024 3rd International Conference on Power, Control and Computing Technologies, ICPC2T 2024, 2024, Vol., , p. 529-534https://doi.org/10.1109/ICPC2T60072.2024.10474952https://idr.nitk.ac.in/handle/123456789/29090This 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.Dynamic modellingnon- isolatedsteady-state analysisUnidirectional high-gain DC-DC converter
