In this paper, a seven-level cascaded H-Bridge dynamic voltage restorer (CHDVR) is proposed to mitigate power quality issues in the power system that are causing severe problems both in industrial and commercial sectors which may sometimes lead to interruption of power. To improve the voltage quality, many series compensators are been using in which DVR is one best solution wherein in many cases phase angle jump is not considered during the initial stage of compensation which influences the power quality. In this paper voltage Phase Angle Jump (PAJ) is taken into consideration to improve voltage quality using DVR. Moreover, Fault riding capability (FRC) is also considered along with phase jump to progress overall execution of the power system. The control strategy adopted is worked out for several sag cases and the analysis is validated using results acquired from MATLAB/SIMULINK 2019 platform.
