  • Industrial power system faults

    Creator:
    Badr, Ahmad Mohamad Amin
    Abstract:
    The purpose of this thesis is to represent and calculate unsymmetrical secondary faults on a grounded wye-to-delta transformer bank. This thesis is specifically concerned with the secondary connections often encountered in industrial installations. Faults on these systems have not been adequately investigated. Three types of faults are considered, namely: 1....

  • Design of self-synchronized asynchronous sequential state machines using asymmetrical delay elements

    Creator:
    Kirkpatrick, Donald C.
    Abstract:
    A design style is presented for a self-synchronized, multiple input change, asynchronous state machine which processes input changes at a speed limited only by the required machine behavior and implementation technology. This state machine will operate at this ultimate speed because of a new asynchronous delay element with unequal rising...

  • Sensitivity analysis and architectural comparison of narrow-band sharp-transition digital filters

    Creator:
    Kulkarni, Satish S.
    Abstract:
    Due to advances in high-density low-cost VLSI and communication technology, digital filtering and signal processing are being widely used for real-time signal processing applications. Given the filter specification, choosing the best filter structure for a given application is not a trivial task. The choice of a particular filter structure depends...

  • High speed digital FIR filter design

    Creator:
    Zhou, Bo
    Abstract:
    The objective of this thesis is to design a high speed digital FIR filter. The inputs of the system come from a Delta-Sigma modulator. This FIR filter takes 1024 inputs, multiplies them with their coefficients and adds the results. The main design task is to take the input data, which...

  • 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...

  • Low noise FSCL digital circuits for decimation filter

    Creator:
    Wong, Man Wa
    Abstract:
    A new circuit technique called Folded Source Coupled Logic (FSCL) has been developed to implement the digital section of mixed-signal IC applications. This FSCL circuit technique offers the advantage of low overlap current spikes during the switching transitions of conventional CMOS gates. This overlap current spike has become one of...

  • 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...

    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...

    Chis, Lucian
    Abstract:
    A relatively new development in the electric machines field has been the written-pole technology, of which the latest product is the large single-phase electric motor, the single phase Written-Pole Motor (WPM). The WPM is a synchronous, permanent-magnet single-phase motor having a weak rotor cage for start-up which in addition exhibits...
