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.

Sequence analysis based DSP controller for Dynamic Voltage Restorer (DVR)
2008 IEEE Power Electronics Specialists Conference, 2008 The paper examines the behaviour of a dynamic voltage restorer (DVR) under balanced/unbalanced supply voltage sag condition, and restricted DVR injection capability (e.g. limited to 50% of the supply voltage injection). Sequence components of the supply voltage are extracted to generate the reference injected voltage for the DVR. The control determines
