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.

Simple, fast detector for voltage dip or voltage swell
Electronics Letters, 2007 A simple, fast detection scheme for voltage dip and voltage swell is presented. Applying a simple relay and lowpass filter to the supply voltage signal, an in-phase fixed magnitude reference signal with very low total harmonic distortion can be generated.
