Analysis on Basics of Modulation Techniques for AC Drive on Efficiency Improvements

This paper reviews the analysis of modulation techniques on A.C inverter in relation to harmonic pollution and reliability. Modulation techniques applications, advantages and disadvantages has been discussed, and methods of implementation are highlighted. Inverters have been faced with harmonic contents pollution in its output current and voltage waveforms. In comparison of different modulation techniques, Key Performance Indicator (KPI) is less time of execution, cheaper or cost-effective method, of implementation are the selection criterion. Modulation techniques discussed were applied on a Single-Phase topology on a full-bridge inverter. It has been proved from the analysis that, a Sinusoidal pulse width modulation (SPWM) technique, shows to be the best method that meet the selection criteria of modulation technique in this paper. The findings on modulation techniques are based on literature review and no experimental work has been conducted.
