Abstract: Voltage distortion is one of the foremost problems now a day. To protect the system and reduce the fixed compensation different filter technologies are used. Still, by using filter technology consumer’s dream towards power quality are not fulfilled. To overcome this drawback and enhance the system reliability, a new technology custom power devices is used. Among the different devices, dynamic voltage restorer (DVR) is a predictable and successful device to mitigate the voltage correlated issues under fault. When the distortion arises, control strategy plays a significant role. Among different control strategies, synchronous reference frame is simple and suitable for DVR. In this literature, the analyses of total harmonic distortion using different controllers are explained in detailed manner. The DVR topology is validated by using MATLAB/SIMULINK.
