Harmonic Analysis of Inverter Topologies for Single Phase Stand-Alone Photo Voltic System

The growing global demand of energy in the last few decades had a significant impact on the climatic conditions such as pollution, global warming, and impact on ozone layer etc. Most reliable type of the renewable energy i. e. Solar Energy is utilized for powering utility in the proposed work of this paper. Many efforts has done to improve the performance of the system with minimum losses, distortion and as possible as the maximum efficiency by using different topologies of multilevel inverter and with different levels. All have their own benefits and limitations. Therefore in this paper comparative analysis and simulation of a various multilevel inverter fed by Solar Photo Voltaic array based on Phase Opposition Disposition Pulse Width Modulation (PODPWM) technique is presented. The solar PV system used is modeled in SIMULINK library present in MATLAB
