Abstract – Improved and controlled power quality is one of the necessary fundamental in any electrical industry for the utilization of resources. On the other hand critical problems in power quality have been predictable such as sags, swells, harmonic distortions and some of the interruptions. These sags and swells are found and have collision on the electrical devices and electrical machines. So needs to be compensated to failure. The DVR is one of the tradition power device used for the compensation of voltage sag and swell with an advantage of active/reactive power control.
A most important volume of literature reported in past quite a lot of years on different configurations of DVR and different control technique used in it which have been describe in this paper. In context of this a detailed review on DVR has been presented with different possible power circuit topologies and control techniques available to reconcile these power quality issues. In this paper will put in in better selection of control policy DVR for a particular requirement.
