DVR is an IGBT based converter system connected in series between the utility grid and to the load. It protects the load from the voltage disturbance by providing fast, accurate voltage correction for the sag, swell and harmonics, as well as maintain the continuous load voltage regulation. The load voltage is continuously monitored and controlled to supply the rated voltage for the load, it requires no energy storage as it draws additional power from the grid to perform its desired action.
