Resource Type:: Dissertation
Full Text:: AN ABSTRACT OF THE THESIS OF Shibashis Bhowmik for the degree

Creator:: Bhowmik, Shibashis
Abstract:: The advent of superior power semiconductor devices and converter topologies has renewed interest in ac drive systems. Although considerable research efforts have gone into improving power electronic converter devices and topologies, very little has been reported on the overall performance optimization of induction machine drive systems. The report of the...

Full Text:: Stator Design and AC/AC Converter Selection for Brush less Doubly-Fed Machines by Shibashis Bhowmik

Creator:: Faveluke, Alex
Abstract:: An AC/AC converter has been designed and implemented for the purpose of providing a modular drive system with a Brushless Doubly-Fed Machine (BDFM.) This converter is to be used in laboratory testing and also as part of a demonstration system in the field. All hardware needed to start and run...

Creator:: Salim, Mohamed Ali, 1968-
Abstract:: Brushless Doubly-Fed Machines have potential benefits in variable speed generation and adjustable speed drive applications by combining a robust machine structure with a reduced power converter rating. While recent work has demonstrated feasibility, steady-state performance has not been optimized. The nature of doubly-fed operation causes rotor currents of varying, relatively...

Creator:: Javadekar, Virendra S.
Abstract:: The loads on the electrical systems of automobiles are projected to increase significantly in the near future. This will result in a requirement for improved efficiency over the present-day car alternators. An alternative scheme proposed at Oregon State University employs a Brushless Doubly-Fed Machine (BDFM) as an alternator. This thesis...

Creator:: Zhou, Dongsheng, 1964-
Abstract:: This thesis presents the development of dynamic control strategies for the brushless doubly-fed machine (BDFM). A simple open-loop scalar controller is first investigated and its response is found to be oscillatory. Using the speed feedback signal, an improved closed loop scalar control algorithm is designed. Steady state performance is controlled...

Creator:: Thompson, Brenda E.
Abstract:: Brushless Doubly Fed Machines (BDFM) have potential advantages in variable speed generation and adjustable speed drive applications. The most significant of these advantages is a reduction in the power electronic converter rating, and therefore a reduction in overall system cost. Presently, efforts are being directed at optimizing the design of...

Creator:: van Zyl, Annabelle
Abstract:: The awareness of electric power quality has increased over the past decade as electronic equipment has become more susceptible to power disturbances. The most disruptive power disturbances are voltage sags and momentary interruptions and their effect on adjustable speed drives (ASDs) is studied in this thesis. Several solutions have been...
