Abstract—This paper deals with simulation and implementation of three level inverter based Dynamic Voltage Restorer(DVR). The control of DVR that injects a voltage in series with a distribution feeder is presented. DVR is a power electronic controller that can protect sensitive loads from disturbances in supply system. DVR can regulate the voltage at the load. Laboratory model is developed and the experimental results are compared with simulation studies.

Index Terms—Dynamic Voltage Restorer(DVR), Matlabsimulink, Series Compensation, Three level inverter.
