Harmonic Reduction Using Multilevel Inverter Concepts
نویسندگان
چکیده
Solar energy sources are widely available, but in the form of DC source. It is connected in distribution system by means of converting DC/AC supply. It is achieved by means of inverter. To get efficient AC source we use multilevel inverter (MLI). The popularly used inverter is cascaded H-bridge MLI. As the step increases, the AC output nearly becomes same as sinusoidal. The purpose of the project is achieving nearly sinusoidal waveform, so that the grid interfacing is easily connected with 3 phase 4 wire distribution system. We can compare the THD values of symmetrical and Asymmetrical cascaded H bridges. This scheme is demonstrated with MATLAB/SIMULINK. Keyword: Multilevel Inverter, Cascaded H-bridge MLI, SPWM.
