Abstract

This work proposes an enhanced sliding mode control (ESMC) strategy for parallel-integrated boost converters (PIBC) employed in a single-stage power conversion system for hybrid solar-wind energy applications. The key novelty lies in the adaptive edge layer-based ESMC, which effectively suppresses chattering without sacrificing the fast dynamic response characteristic of conventional sliding mode control (SMC). By directly interfacing photovoltaic (PV) and wind energy sources through a single-stage converter, the proposed architecture eliminates intermediate power conditioning stages, thereby reducing system complexity and improving conversion efficiency. The proposed ESMC ensures robust voltage regulation and improved power quality under fluctuating renewable inputs and load disturbances, addressing a critical challenge in hybrid renewable energy systems (HRES). Unlike traditional SMC and sinusoidal pulse-width modulation (SPWM)-based approaches, the proposed method adaptively responds to input variations while maintaining stable and reliable operation. The effectiveness and robustness of the ESMC-based PIBC are validated through simulation and experimental investigations, demonstrating its suitability as a high-performance and scalable solution for efficient power conversion in HRES.
