The present paper focuses on the development of a topology for single-phase grid connected inverter based
on Photovoltaic generation. The work initiates with mathematically modeling a PV solar cell and studying its
performance under varying environmental and physical conditions through P-V and I-V characteristics. Fuzzy Logic is
developed as maximum power point tracking to overcome the drawback of poor efficiency of PV cells. Thus,
implementing fuzzy logic, maximum power is extracted to revamp the PV cell efficiency. For grid connections,
unregulated DC output of PV module needs to be regulated and elevated using DC-DC flyback converter. Finally, singlephase inverter will be synchronizing with grid using SPWM switching technique. The simulation work is performed using
MATLAB/SIMULINK tool and results are presented.
