Abstract : Cascaded H-bridge multilevel inverter is a promising topology and is increasingly being considered for high power applications because of their ability to operate at higher output voltages while producing lower levels of harmonic components in the switched output voltages. A small total harmonic distortion is the most important feature of these inverters. This study compares the total harmonic distortion in 5, 7, 9 and 11 levels of cascaded H-bridge multilevel inverter employing sinusoidal pulse width modulation control technique and photovoltaic power source as input to the system. Fuzzy logic controller is used to control this system to get the required output voltage. The results gained in this research prove the validity of the proposed controller of having an output voltage with minimum distortion. Hence, the efficiency of the system will be improved. The analysis has been studied by the MATLAB/SIMULINK. The simulated output shows very favorable result.
