Abstract

A new 15 level inverter is presented in the paper to improve the solar photovoltaic (PV) grid integration process. Improved substantially in the pattern of waves quality with the current THD 3.91%, and voltage THD to 15.77%. Due to its efficiency the design is able to achieve a power conversion efficiency level of 96.75%. The reductions in switches to seven devices is successful and allows for the operational simplicity and cost effectiveness. MATLAB/Simulink simulations have been used to comprehensively revalued the suggested inverter design performance in terms of its operational characteristics and functionality. And the simulation tests looked into analyzing the PV grid connect while considering a group of operational conditions. The results of the test indicate that the proposed system will be able to operate in real life condition because it provides good results in terms of grid stability and dependability with a smooth connection to the grid. Improvements in inverter technology to achieve high efficiency would be facilitated by research presented here that further refines integration method for solar PV systems that requires less operational complexity and better grid integration
