Now a days, maximum industrial devices are mainly supported electronic devices like programmable logic controllers and electronic drives. The electronic devices are really sensitive to disturbances and subsided tolerant to power quality problems like voltage sags, swells and harmonics problems . Voltage dips are thought of to be one in each of the foremost severe disturbances to the industrial equipments. Another power electronic resolution to the voltage regulation is that the use of a dynamic voltage restorer m(DVR). DVRs are a class of custom power devices for providing reliabledistribution power quality. Power Quality problems comes as an outsized vary of disturbances like voltage sags/swells, flicker, harmonics distortion, impulse transient, and interruptions
