Design of a Cascaded Single-Phase Multilevel Inverter for Photovoltaic Applications

Abstract:

Nowadays, obtaining alternative forms of electrical power is a topic of worldwide interest, since fact that dependence on non-renewable resources such as hydrocarbons, coal, and uranium is becoming more and more costly due to their depletion. An alternative solution to this problem is the generation of electric energy by means of the use of solar energy captured by solar panels and the use of multilevel converters for the conversion to AC, which is how it is normally used in the home and industry. In this paper, we start with the review of the state of the art of the cascade multilevel inverters (CHMLI) and the modulation techniques commonly used for these inverters. Subsequently, the single-phase CHMLI is designed and simulated using MATLAB/Simulink software. To improve the signal quality, Butterworth filters were used for both the input and output of the CHMLI, resulting in an almost pure sinusoid with a very …
