Mandal, S.Prabhakaran, P.Adib, M.2026-02-062024Proceedings of the International Conference on Power Electronics, Drives, and Energy Systems for Industrial Growth, PEDES, 2024, Vol., 2024, p. -28363841https://doi.org/10.1109/PEDES61459.2024.10961618https://idr.nitk.ac.in/handle/123456789/29162This paper presents a novel non-isolated high-gain DC-DC converter engineered for optimal efficiency. This converter boasts a remarkably simple structure and employs a minimal number of components. Its standout characteristic is its wide duty ratio range, which significantly enhances adaptability to suit the diverse requirements of renewable energy sources (RES) and electric vehicle (EV) applications. The proposed converter integrates the quadratic boost and modified Cuk converter designs to obtain enhanced gain and performance. Additionally, this converter offers the advantage of utilizing just one switch, leading to simplified circuitry and reduced complexity. Furthermore, the voltage stress across the switch is maintained at a low level, contributing to improved reliability and reduced cost. A brief analysis and simulation results are presented to validate the efficacy of the proposed converter. © 2024 IEEE.DC-DC convertersElectric VehiclesHigh-gain DC-DC ConverterModified Quadratic Boost and Cuk (MQBC) ConverterRenewable Energy SystemSingle-Switch
