This paper proposes a three phase topology as dynamic voltage restorer. In this work, a series active filter is explored as dynamic voltage restorer to correct the quality power. Using the proposed design, the voltage compensation has been verified for a three-phase system with non-linear load. The simulation has been done using MATLAB/Simulink. The proposed method provides better results as voltage regulator for unbalanced applied input voltage. With the increase of nonlinear loads in the power system, more and more filters are required. Thus, dynamic voltage restorer is designed and analyzed to improve the power quality at ac power supply.

Keywords: Dynamic voltage restorer, series active filter, load voltage, total harmonic distortion, three phase network.
