Abstract

In most areas and power systems, Photovoltaic (PV) energy is rapidly becoming a significant component of the energy balance because of its rapid annual growth rate. Therefore, this research presents the PV-fed improved SEPIC-Zeta converter with a cascaded fuzzy algorithm based Maximum Power Point Tracking (MPPT) for efficient DC power transfer. At the beginning, the improved SEPIC-Zeta (ISZ) converter is exploited to enhance the PV system’s voltage. Then, the Cascaded Fuzzy MPPT algorithm is introduced for tracking the upmost power from PV system. Also, the high frequency inverter transmutes the DC to AC power and isolation is provided by the isolation transformer for ensuring safety and mitigating harmonic distortion on the source and load side. Additionally, the interleaved synchronous rectifier is exploited for converting the AC into a DC supply. The implemented research is validated in MATLAB tool, which demonstrates that the proposed work has a converter efficacy of 95.12 %, which handle fluctuations and disturbances more effectively, enhancing the reliability of overall system.
