Objectives: This paper deals with the power system problems like sag, swell and also improve power quality of the three phase system. Methods: Previously many compensating devices were used to improve the power quality of the system. Here the detailed analysis of matrix converter can be used to improve the power quality in the three phase system. Findings: The matrix converter is introduced as the compensating device. The major advantage of matrix converter is the elimination of dc link capacitor. These DC-link Capacitors results in an inefficient compensation of the system. By implementing the new strategy of using matrix converter as IUPQC the power quality is improved efficiently than the conventional methods. Applications: This system is designed for the power quality improvement in the three phase system.
