A new development of voltage control scheme for power quality improvement such as voltage sag, swell, harmonics, and transient conditions in three-phase power systems has been proposed. Faults occurring in power distribution systems or amenities can inject the voltage sag or swell. This fault can damage or affect the power transmission and distribution. For sensitive loads, the short duration of voltage sags also cause huge problems in the entire power system. In order to reduce power interruptions, this work proposes a novel Zeta converter based DVR system. This proposed scheme can quickly access the voltage sag and swell under transient condition.
