| description | This paper addresses the challenges by enabling a novel Interleaved Boost-SEPIC converter (IBSC) for improving the Photovoltaic (PV) system’s performance, controlled by a passivity-based proportional integral control strategy. The use of non-interleaved converters in PV systems leads to reduced efficiency due to challenges in controlling high-frequency switching, potentially resulting in decreased energy conversion efficiency and increased losses. Additionally, non-interleaved converters may exhibit weaker transient response characteristics, leading to slower voltage regulation and potential instability under varying load conditions. There is also a higher risk of electromagnetic interference (EMI) with non-interleaved converters, which can interfere with other electrical systems and equipment. The main objectives of the study are to improve PV system’s performance by enhancing energy conversion efficacy and to provide stable outcomes with improved transient response. These objectives were achieved by the proposed IBSC, controlled by a passivity-based PI controller which aims for efficient regulation of converter voltage output, ensuring high efficiency and rapid transient response. The control scheme utilizes the converter's passive features to guarantee stable operation under various operating conditions. MATLAB simulations establish the robustness of recommended control system, the most important results are rapid transient response of 0.5s, high efficiency of 91% and robust performance for the Boost-SEPIC converter in PV systems. The significance of obtained results includes improved energy conversion, stable voltage regulation and enhanced reliability. On comparison, the proposed concept outperforms conventional ones in terms of efficiency, ripple reduction and stability making it a better solution for improving PV system performance. |
