Energy efficiency enhancement using dynamic voltage restorer (DVR)
International Journal of Power Electronics and Drive Systems (IJPEDS), 2019 Dynamic voltage restorer (DVR) is a device that can compensate harmonic, voltage sag and voltage swell condition that exists in a three-phase system. Other than that, DVR can also be used to enhance the energy efficiency or energy saving by reducing excessive amount of incoming power via the reduction incoming voltage at allowable limit.
