Abstract

A High step-up modified SEPIC converter is proposed in this research work with Sun Flower Optimization (SFO) based maximum power tracing controller under dynamic operating condition to trace maximum power from solar PV. The proposed converter is designed to perform under various working conditions like steady state condition, variable solar irradiance condition and variable load condition. The proposed converter is designed to handle a 100W, 24 V solar panel. The maximum voltage conversion ratio achieved by this converter is 7.92 and output voltage yielded is 190 V. The maximum conversion efficiency achieved by this converter is 95.63%. This converter finds application in multi-source fed hybrid electric vehicle applications. The simulation analysis is carried out using MATLAB/R2022a Simulink tool and the real time experimental prototype is implemented in the laboratory to validate the simulation and theoretical analysis.
