The dynamic voltage restorer (DVR) is a power electronic based device that is used to boost the voltage supplied to the sensitive loads during voltage sags. A DVR consists of an energy storage unit, a voltage source converter, a filter, a coupling transformer and fi nally the controller system. From its fi rst unit installed in 1996, several confi gurations, compensation strategies and controllers have been presented in literature, aiming at fast response, accurate compensation and low costs. In this paper, a literature review is presented scanning the most important contributions in this topic.

The Dynamic Voltage Restorer (DVR) is fast, flexible and efficient solution to voltage sag problem. The DVR is a power electronic based device that provides three-phase controllable voltage source, whose voltage vector (magnitude and angle) adds to the source voltage during sag event, to restore the load voltage to pre-sag conditions. The DVR is designed for protecting the whole plant with loads in the range of some MVA. The DVR can restore the load voltage within few milliseconds. Several configurations and control methods are proposed for the DVR. In this paper, an overview of the DVR, its functions, configurations, components, …
