Comparing Total Harmonic Distortion in Different Space Vector Modulation Techniques for Asynchronous Motor Drives Using Direct Matrix Converters

This paper discusses the space vector modulation techniques used in direct matrix converters. Traditional modulation techniques used in matrix converters have limitations, such as poor power factor and high total harmonic distortion. The proposed modulation control strategies, on the other hand, offer several advantages, like an input power factor close to unity, and total harmonic distortion is also reduced by the designed filter. The proposed system is tested through simulation studies using different SVM techniques. In this paper, a comprehensive analysis is presented, focusing on the comparison of total harmonic distortion (THD) in line-to-line voltage and output line current between direct space vector modulation (DSVM) and indirect space vector modulation (ISVM) techniques applied to a direct matrix converter. The study concludes by highlighting the advantages and disadvantages of these modulation techniques. This direct space vector modulation technique is implemented using the OPALRT LAB.
