Heuristic analysis of brackishwater treatment by reverse osmosis process
(
Qatar University
, 1990 , Article)
Treatment of brackish water and sea water with the help of reverse osmosis process is feasible and a viable solution to meet the fresh water deficiency in an arid region. Total dissolved solids can be reduced to a level ...
Evaluation of a multilevel cascaded-type dynamic voltage restorer employing discontinuous space vector modulation
(
IEEE Industrial Electronics Society
, 2010 , Article)
In this paper, the application of a cascaded multilevel inverter as a dynamic voltage restorer (DVR) is investigated. Two discontinuous multilevel space vector modulation (SVM) techniques are implemented for DVR control ...
