A low cost AC motor drive for battery powered applications

Creator:: Wiley, Brian
Abstract:: Environmental concerns have renewed the interest in electric vehicles. To gain widespread use, electric vehicles will also have to offer good performance and be reasonably priced. AC drive systems using modern semiconductors can provide efficient operation at the required power levels, but their cost at present is still too high....

Finite element based rotor design optimization for the brushless doubly-fed machine

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...

Design and development of a controller for a brushless doubly-fed automotive alternator system

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...

Direct torque control for brushless doubly-fed machines

Creator:: Brassfield, William R.
Abstract:: The Brushless Doubly-Fed Machine (BDFM) has recently become an important research topic in the field of variable-speed AC drives. In recent studies, the BDFM has shown significant potential for improving the reliability and performance of AC drive systems, as well as reducing total system cost. While the BDFM offers several...

Design studies relating to the brushless doubly-fed automotive alternator

Creator:: Ravi, D. K.
Abstract:: The alternators in today's automobiles are of the claw-pole or Lundell construction, which is a readily manufactured, low-cost derivative of the conventional rotating dc field synchronous generator. The efficiency of the Lundell system is low due to a complicated magnetic circuit of predominantly solid steel and a high windage rotor...

System optimization studies related to stator design and AC/AC converter selection for brushless doubly-fed machines

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...

Evaluation of dynamically controlled resistive braking for the Pacific Northwest power system

Creator:: Raschio, Peter J.
Abstract:: Today's power systems are undergoing dynamic changes in their operation. The high cost of capital improvements that include new generation and transmission projects has prompted power system planners to look for other alternatives in dealing with increased loads and overall system growth. A dynamic braking resistor is a device that...

Dynamic control of brushless doubly-fed machines

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...
Resource Type:: Dissertation

The development of commercially viable brushless doubly-fed machines

Creator:: Bellagh, Robert L.
Abstract:: Basic operation, as well as successful development, of the Brush less Doubly-fed Machine (BDFM) has been documented, and research has turned from proof of concept and early development to the more practical direction of increased manufacturability to prove industrial viability. Previous research centered on using standard induction motor stators along...

Hardware design and protection issues in an AC/AC converter

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...
