Characterization of the Pulse-Width Modulation (PWM) Techniques Applied to Three-Phase Inverters

Abstract

A three-phase inverter is a device that generates a sine wave signal with variable amplitude and frequency based on DC sources. This device is a critical part of the electrical actuation responsible for speed control applications in the industry. Currently, researchers are experiencing difficulties when trying to compare the different modulation techniques of three-phase inverters reported in existing literature. As a response, the present article proposes a set of characteristics to facilitate this comparison. From the analysis of pulse-width modulation (PWM) techniques, the article proposes a classification scheme based on five characteristics. This group of characteristics is expected to facilitate the process for comparing modulation techniques as well as the development of new algorithms that contribute to new proposals in this area
