Simulation and analysis of the harmonic behavior of matrix converters as compared with conventional converters

Abstract

The type of the electronic converter used in a set based on power electronics has an important role in the performance of the set. For example, the quality of the converter in the drive system of a motor has a direct influence on the performance of the motor. In recent studies, the use of matrix converters in the drive system of motors has yielded very desirable results. One of the most important positive aspects of these converters, which has not been independently and thoroughly studied yet, is the quality of the signal produced with regard to the harmonic content. This is a very important subject in cases such as the drive system of electric motors, and if it is not taken into account in the design, serious problems will result. Due to the importance of the subject mentioned, this positive aspect of the matrix converters is independently studied in this article. To this end, the quality of the output signal of a two-phase matrix converter is studied and comparisons are made to clarify the relative superiority of this converter over conventional ones. Key words: matrix converter, total harmonic distortiontotal (thd), conventional converter, harmonic behavior.
