    Abstract: This study proposed a novel design of Multilevel PV Inverter for Grid Connected System which is named as Center-tapped primary winding transformer based five level inverter (C-T<SUP>2</SUP> Inverter). The design of C-T<SUP>2</SUP> Inverter is aimed to reduce the number of components is directly proportional to reduction in the power losses, size and cost. The proposed three phase inverter is driving only by the Single dc supply that is each phase is parallel connected to the same dc input source. Finally, the grid synchronization is made by using Space Vector Pulse Width Modulation (SVPWM) which enhances the power quality indices like Power Factor (PF) and Total Harmonic Distortion (THD).
