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....

A programmable BiCMOS transconductance-capacitor filter for high frequencies

Creator:: Beck, Jeffery S.
Abstract:: With advancements in CMOS technology, high speed analog circuits that were traditionally implemented with discrete circuit components can now be made monolithically. Antialiasing filters for video signals as well as signal conditioning filters in high speed communication channels are examples of applications where high frequency integrated circuits are now feasible....

Characterization studies and industrial control development for the brushless doubly-fed machine

Creator:: Koch, Brian
Abstract:: This thesis presents the development of a supervisory controller for a pre-commercial Brushless Doubly-Fed Machine (BDFM) drive system. In addition, characterizations of new diecast rotors for the BDFM are presented. Using the characterization results from the new rotors, a control scheme was developed to allow a BDFM to be packaged...

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...

Design of CMOS switched-current filters

Creator:: Fiez, Theresa S.
Abstract:: The design and implementation of Switched-Current (SI) ladder filters is described. SI filters require only a standard digital CMOS process and the power supply voltage requirement is low. SI circuits also can be potentially operated at higher frequencies than Switched-Capacitor (SC) filters due to the low-impedance wideband nodes of the...

Design of switched-current circuits for a bandpass delta-sigma modulator

Creator:: Manapragada, Praveen
Resource Type:: Masters Thesis
Full Text:: a switched-current bandpass delta-sigma modulator. This thesis presents the design and layout of a

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...

Development of a 300 Hp regenerative motor and generator test facility

Creator:: Lewis, Timothy M. (Timothy Michael)
Abstract:: A 300 hp motor and generator testing facility is being completed at Oregon State University. The testing center is the largest independent testing facility west of the Mississippi River. This regional resource center will incorporate state-of-the-art features that set it apart from other testing facilities. An induction machine with a...
