Maximum voltage sag compensation using direct converter by modulating the carrier signal

Rahman, S. Abdul; Teshome, Gebrie (International Journal of Electrical and Computer Engineering (IJECE), 2020-03-01)

The aim of this paper is to achieve maximum voltage sag compensation of 52% using direct converter based DVR. The DVR topology has only two switches. The DVR is designed to compensate the voltage sag in a phase by taking ...
Voltage Sag Mitigation Using Direct Converter Based DVR without Error Signal

S. Abdul, Rahman; Dagnew, Estifanos; Birhan, Shumye; Teshome, Gebrie; Asmare, Mekete; Mesfin, Solomon (PRZEGLĄD ELEKTROTECHNICZNY, 2021)

Abstract- Dynamic voltage restorer is considered to be one of the best device to compensate voltage sag and swell. Recently the DVRs based on direct converters are very popular and works are getting published for various ...
