A dynamic voltage restorer (DVR) based on an AC-AC converter is presented. It is able to compensate different common disturbances in distribution systems, with the purpose of improving the power quality delivered to the users. A prototype has been assembled to test the feasibility of the proposition. In this paper a modulation strategy based on the well known space vector modulation (SVM) algorithm is presented in order to synthesize controllable voltages in magnitude and waveform for compensation purposes. Unbalanced and harmonic distortion conditions in the supply voltages are taken into account. These results positively confirm the design, simulation, assembling, and expectations about the device.

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