Abstract

This paper analyses the harmonic reduction of multilevel inverter for grid connected solar system. Solar array is controlled and maximum power is obtained by FLC MPPT algorithm. Sinusoidal Pulse Width Modulation (SPWM) is used to control the inverter and simulation is achieved through MATLAB/Simulink. The simulation results of three phase three-level and five-level inverter is compared and low THD rate is achieved for high level inverter.
