Abstract
Incredible advances taking place in medium and high-powered applications of electric sector, different topologies of converters are flagging the way into it. Multi-Level Inverters (MLI) is one of the converters which deal with many applications by generating desired level of output voltages with various Pulse Width Modulation techniques. In this paper, a fifteen-level inverter has been discussed by using Sine wave Pulse width modulation technique along with Pulse Disposition (PD) modulation method to decrease harmonic content. Chosen switching patterns are given to MLI by designing suitable logic gate circuit. A detailed explanation on generating switching patterns by logic gates with binary coded representation, output voltage waveforms of inverters along with THD analysis are given in this paper with the help of MATLAB/SIMULINK.
