Principles and latest progress of Doubly Fed Brushless Machine (DFBM) are reviewed with the identified solutions to designing a high efficiency DFBM of 96%. The original design of DFBM rated at 200kw/1200rpm focuses on the key components of DFBM, including the rotor style and pole number combination, and control algorithms. Both theoretical and experimental results are presented to substantiate the success of the original design solutions.Keywords-doubly fed, brushless, high efficiency, decouple control of active and reactive power, wind power generator
Yazan Alsmadi received the B.S. degree (Summa Cum Laude) in electrical power engineering in 2010 from the Yarmouk University, Jordan, where he ranked 1st in his class. He received Yarmouk University Presidential Award for Academic Distinction in 2009 and Jordan Ministry of Higher Education and Scientific Research Award for Academic Distinction in 2007. He is currently working toward the Ph.D. degree in electrical and computer engineering at The Ohio State University (OSU), Columbus, OH, USA. He was nominated for the Graduate Associate Teaching Award (GATA) at OSU, the university's highest recognition of the exceptional teaching provided by graduate students at Ohio State University. His research interests include integration of renewable energy resources into electric power systems, advanced control theory of distributed power and variable speed systems and development of power electronics systems for renewable energy applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
