The hybrid renewable energy systems are widely employed to meet the load demand at various critical times. This paper proposes the modelling, simulation, and conversion of energy using multiple power electronic based DC-DC converter topologies in Hybrid Renewable Energy System (HRES) which consist of solar and wind turbine energy sources, for enhancing the system stability and efficiency. This work presents a novel high gain power electronic DC-DC known as Modified Single-Ended Primary-Inductor Converter with magnetic coupling for boosting voltage in HRES. Landsman converter is used to reach peak DC output voltage, improve power quality and voltage stability, reduce conversion of power stages, and decrease losses compared to the present power electronic converter coupled with HRES. Moreover, adaptive neuro fuzzy system controller is proposed in this research to gain peak power from photovoltaic system. The results are validated using SIMULINK/MATLAB software.
