  • 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...

  • 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...
