Abstract: This study a proposed a new series active filter, based on a matrix converter without energy storage devices to mitigate the current harmonics. By connecting the matrix converter output terminals to the load side connected with series transformer and the input side of matrix converter is connected to the supply side. So, a matrix converter injects the compensation voltage on the load-side, so, it is possible to mitigate the voltage sag/swell problems, resulting in an efficient solution for mitigating voltage related power quality problems. Thus, the proposed topology can mitigate the voltage fluctuations without energy storage elements and the total harmonic distortion produced by the system also very low. Space-Vector Modulation (SVM) is used to control the matrix converter. MATLAB/Simulink based simulation results are presented to validate the approach.
