In this paper a new three phase symmetrical multilevel converter for grid connected system using PV source. The renewable energy sources are application of the distributed generation (DG) in the distribution system acquired more attention .The Distribution generation systems are powered by micro sources such as fuel cells, photovoltaic PV) systems, and batteries. PV distributed system in which the solar source is low dc input voltage interfaced to grid using front-end conversion. Three phase Cascaded H-Bridge Seven level inverter is interfaced with low frequency transformer with multiple PV Source is proposed. Nowadays multilevel inverter (MLI) plays a vital role in the field of power electronics and being widely used in many industrial and commercial applications. Moreover the advantages like high quality power output, low switching losses, low electro-magnetic interference (EMI) and high output voltage made multilevel inverter as a powerful solution in converter topology. The proposed topology is suitable for any number of levels. When the levels are increased the number of switches used is reduced compared to the conventional cascaded H-bridge multilevel inverter. This paper is particularly focused on the 13-level inverter with the requirement of low switching components. In the proposed topology only 7switches were used. The harmonic reduction is achieved by selecting appropriate switching angles. It shows hope to reduce initial cost and complexity hence it is opt for grid applications
