MPPT based solar powered cascade multilevel inverter

This paper presents a 11 level cascade multilevel inverter which implements the popularly used MPPT algorithms Perturb and Observe and Incremental Conductance on the PV array which powers the multilevel inverter. Adaptive Neuro Fuzzy Inference System (ANFIS) based controller switching scheme is used to improve the power quality thus to reduce the Total Harmonic Distortion (THD). The performances are evaluated by means of MATLAB/SIMULINK simulations by implementing Perturb and Observe and Incremental Conductance MPPT algorithm on the PV array and the results in terms of THD are compared.
