Harmonic Reduction In Five Level Inverter Based Dynamic Voltage Restorer

This study deals with harmonic reduction in the five level inverter based Dynamic Voltage Restorer(DVR). The control of DV R 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. The simulation results of five level inverter based DVR are presented. The spectrum for the output voltage is also presented.
