Mitigation of Voltage Sags and Voltage Swells by Dynamic Voltage Restorer [PDF]
International Journal of Electrical and Power Engineering, 2011 Modern industrial processes are based on a large amount of electronic devices such as programmable logic controllers and adjustable speed drives. Unfortunately, electronic devices are sensitive to disturbances, and thus, industrial loads become less tolerant to power quality problems such as voltage sags, voltage swells, and harmonics.
