  • Prediction of brushless DC drive performance considering non-sinusoidal parameter variations and asymmetrical operating conditions

    Creator:
    Spee, Rene
    Abstract:
    A highly flexible numerical simulation model for the performance prediction of brushless dc drives is presented, which is capable of investigating unbalanced and asymmetrical operating conditions as well as drives with non-ideal parameters. Numerical speed-up procedures allow for the investigation of pulse-width modulated (PWM) drives using a personal computer. Experimental...

  • 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...

  • Computerised dynamic control of an ac dynamometer

    Creator:
    Rodrigues, Terence Keith
    Abstract:
    The Motor Systems Resource Facility (MSRF) at Oregon State University presently conducts a variety of steady state tests on Motors and Generators, with ratings of upto 300Hp.(225kW), using a dynamometer. The dynamometer consists of an induction motor fed by a power electronic converter. A control computer uses a serial link,...

  • 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....

  • Performance and parameter prediction of large synchronous machines from physical dimensions

    Creator:
    Heberle, David D.
    Abstract:
    A project funded by the Southern California Edison (SCE) Company, Research Center of Irwindale, California, has supported the development of a performance and parameter prediction software program for use during the refurbishment of large synchronous machines, turbine generators, and synchronous condensers. The computer program was developed for SCE to allow...
