  • 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...

  • 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,...

  • 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...

  • Hybrid electric vehicle converter harmonics

    Creator:
    Bowers, Waylon T.
    Abstract:
    Hybrid electric vehicles (HEV’s) are a very important part of today’s transportation system as they are bridging the gap between fully electric vehicles and conventional internal combustion vehicles (ICV’s). They have much higher efficiencies and lower emissions than ICV’s, while still having the ability to travel long range and refuel...

  • Hybrid electric vehicle dc-bus converter harmonics

    Creator:
    Mills-Price, Michael A.
    Abstract:
    As more advanced hybrid electric vehicles begin emerging onto the commercial market, design algorithms for their control become increasingly more complicated. One major hurdle for designers is the mitigation and control of the created high frequency harmonics caused from switching the dc voltage into an ac voltage by use of...
