Multifunctional Dynamic Voltage Restorer (DVR) – An Overview

Abstract

Power quality becomes an awfully necessary issue owing to rapid climb within the use of
nonlinear hundreds. Power quality is just a curving voltage and current wave specifically in
part with constant frequency, if there square measure any deficiencies in voltage or current
wave then there exists issues in power quality. Owing to this impact, cable voltage and
current wave gets distorted. The varied power quality issues on the gear square measure
voltage sag, voltage swell and harmonics. Within the projected work, dynamic voltage
preserver that is employed to compensate voltage sag and swell victimisation series injection
electrical device that is connected across the cable, it conjointly performs multi-functional
mode of operation.
