Dynamic Voltage Restorer Using AC Chopper for Distribution System
Sudhakar M

This paper deals with modelling and digital simulation of AC chopper 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 of voltage fluctuations in supply system. It is observed that DVR can regulate the voltage at the load. Circuit model is developed for the single phase model and the same is used for simulation studies. It is tested for different capacity loads.
