Effect of PI controller on efficiency of dynamic voltage restorer for compensation of voltage quality problems


This paper describes and demonstrates the effect of a PI controller in a novel design of a dynamic voltage restorer (DVR) which mitigate power quality problems like sags, swell, and phase jumps by injecting minimum active power in system and provides the constant power at load side without any disturbance. Along with PI controller the design of this DVR… (More)
