Fractional Order PID Controlled PV Fed Buck Boost Converter with Coupled Inductor for Battery Charging Systems

solar energy is one of the promising alternate energy sources for easing the strain of fossil fuels. The load control is made better by the PV supplied Buck Boost converter with linked inductor. The many closed loop regulated techniques for battery charging systems are examined in this investigation. The objective of this effort is to enhance the battery charging system’s dynamic responsiveness for the use in electric vehicle applications. Modelling, simulation, and analysis of the resulting data are done for PV fed closed loop controlled battery charging systems. Using a FOPID controller, the suggested system’s performance has improved by means of peak over shoot, settling time, steady state error, and ripple in current.
