Abstract

Voltage sags and swells are vital power quality problems and the dynamic voltage restorer (DVR) is known as an effective device to mitigate voltage sags and swells. The paper deals with the sliding mode control of single phase DVR for voltage sag/swell correction. A sliding mode controller is designed and developed for a single phase DVR. Using sliding mode control to the DVR, additional sag/swell detection method is eliminated. This improves the dynamic response of the DVR and also DVR is able to compensate for any variation in source voltage. Usage of sliding mode control to DVR, makes it multifunctional, such as compensation for voltage sag, swell, voltage flicker and voltage harmonics as well. Validity of the proposed control is verified through extensive simulation and experimental results
