A dynamic voltage restorer (DVR) with no energy storage is studied. By using a matrix converter instead of the conventional\r\nAC/DC/AC converters, elimination of the DC-link capacitor is possible. The switching algorithm of matrix converter is the space\r\nvector modulation. There are different compensation algorithms to control the conventional DVR. These methods have been\r\nanalyzed in this paper for the proposed matrix-converter-based DVR. A deep analysis through different diagrams would show\r\nthe advantages or disadvantages of each compensation method. Equations for all methods are derived, and the characteristics of\r\nalgorithms are compared with each other.
