Harmonics Mitigation Of P&O MPPT Based Solar Powered Five-Level Diode-Clamped Multilevel Inverter

Recent advancement in modern technology has widely increased the expediency of power, which causes the broadening of conventional sources. So to meet the demand gleaning energy from renewable energy sources have become popular now-a-days. Solar photovoltaic (SPV) technology which converts solar radiation directly into the electrical energy is one of the good choices in renewable energy family. This paper presents a stand-alone SPV system in which designing and simulation of Boost converter connected with diode-clamped multilevel inverter for ac load is presented. Perturb and observe MPPT algorithm has been implemented to extract maximum power. The premier objective is to obtain voltage with less harmonic distortion. Multilevel inverter has changed the scenario in the utilization of renewable energy. Multi-carrier PWM techniques have been implemented and analyzed for modulation scheme. The proposed system is simulated on MATLAB/Simulink platform.
