Dynamic Voltage Restorer (DVR) for Voltage Sag Mitigation
International Journal on Electrical Engineering and Informatics, 2011 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.

Energy efficiency enhancement using dynamic voltage restorer (DVR)
International Journal of Power Electronics and Drive Systems (IJPEDS), 2019 Dynamic voltage restorer (DVR) is a device that can compensate harmonic, voltage sag and voltage swell condition that exists in a three-phase system. Other than that, DVR can also be used to enhance the energy efficiency or energy saving by reducing excessive amount of incoming power via the reduction incoming voltage at allowable limit.
