Issues of Matrix Six –phased Converters: ...

One of the main components of power electronics is matrix converters. A matrix converter is an Ac to AC converter, the structure of which is made up of two-way switches. This converter can be used to feed an AC current with a desirable AC voltage. Matrix converter is a powerful AC/AC converter for the application of induction motor drives with sinusoidal input currents and no DC-link capacitor. It offers remarkable advantages over other alternatives in applications requiring improved utility interaction and critical weight/volume reduction. In this paper, after the initial introduction and classification of the AC/AC converter, firstly the advantages, disadvantages and other particular problems related to the matrix converter have been presented. Then technical review on related issues of induction motor drive fed by matrix converters (MC) is presented. The first discussions presented the special difficulties involved in matrix converters. These are partly conceptual, partly concerning circuit topology, and current commutation technique. Secondly, different types of control and matrix converter control techniques based on the Spatial Vector Modulation (SVM) technique have been discussed. The third discussion describes the hardware development modes studies. And finally, the matrix converter has been simulated using MATLAB software, and output voltage and input current has been obtained with the help of modulation matrices.
