Harmonics Reduction in Solar Inverters by Using Multilevel Scheme Having Level Modules and H-Bridge Inverter

<jats:p>This paper examines and estimates the similarities or dissimilarities of two methods for dc to ac power conversion. Cascaded H-Bridge Inverter is the first approach and new Multi-level Scheme which has H-Bridge and Level Modules. SIMULINK/MATLAB software is used to show the output voltage and current waveforms. Real power, reactive power and the total distortion of harmonics in resultant load voltage developed by the two methods are compared. It is indicated that THD developed in the new multi-level scheme is advantageous up to some stages of the first scheme. And the resultant real and reactive powers are effective for the latter scheme</jats:p>
