The dynamic voltage restorer (DVR) is great significance for improving power quality as a cost effective solution for the protection of sensitive loads from voltage sags. This paper summarizes Sliding Mode Control (SMC) method used in current control strategies for DVR including forward-feed control and PI feedback control. After this paper, it presents SMC for DVR including the design of switch function and control regulation. And the experiment results are presented to demonstrate the efficacy of proposed DVR controller for various voltage sags.
