— Voltage sag disturbances are the most frequently occurring Power Quality problems in the distributionsystem. Dynamic Voltage Restorer is normally employed as a solution for mitigation of voltage sag. The proposed systemhas less number of switching devices and has good compensating capability in comparison with commonly usedcompensators. The Static Series Compensator (SSC), commercially known as Dynamic Voltage Restorer (DVR), is bestsuited to protect Sensitive loads against such incoming supply disturbances. This project presents the hardwareimplementation of single phase Dynamic voltage restorer in mitigating voltage sag and swell. A simple faultgenerated is created which intentionally creates four levels of Voltage disturbances .Single phase inverter based onMOSFET was designed and firing pulse to the device using micro controller based PWM generation. Energy storagedevice used in this work is Battery which acts as input to the inverter. DVR model compensates the voltage sag and swellwith efficient and effective manner, because of its lower cost, smaller size, and fast dynamic response to the disturbance.
