Absolute Sinewave Based Modulation Technique for Reduced Switch Multilevel Inverter for better Total Harmonic Distortion

Abstract

This research presents a unique three-phase design for balanced input sources multilevel inverters. To obtain the voltage output with the least amount of THD, the upgraded H-bridge multilevel inverter uses the absolute sinusoidal method. Leveraging MATLAB/SIMULINK, an investigation for induction motor fed water pump is conducted using this approach for fifteen level inverters. Less switches and uncomplicated control are both advantages of this technology over traditional systems. However, as the amount of level rises, so do the switching components and dc sources. Utilizing hybrid technology to create the inverter solves this problem. The purpose of the present work is to create a hybrid cascaded Hbridge inverter that employs pulse width modulation to require lesser switching devices and dc sources.
