Abstract: Solar energy is a critical aspect of Renewable Energy Systems (RES), driven by increasing cost-of-electricity and growing demand from utility customers for clean, pollution-free, sustainable energy. Distributed Photovoltaic (PV) generation systems generally produce low voltage, thus introducing a high step-up converter to interface efficiently with the load is crucial. Therefore, this paper provides a novel Coupled Inductor Extended Double Stage Active Boost (CIX²AB) Converter for enhancing voltage efficiency in PV system. Also, the Proportional Integral (PI) controller is utilized to regulate the converter and supports stabilization of output voltage. The numerical model of the CIX²AB converter circuit integrated with PV is implemented using MATLAB/Simulink software. The experimental verification demonstrates that the developed CIX²AB converter significantly contributes in achieving higher efficiency of 96.2% with enhanced voltage gain and reduced stress.
