  • 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...

  • Computing Substation Fragility as a Function of Seismic Component Failure

    Creator:
    Stark, William D.
    Abstract:
    The electrical grid of the Western Interconnection is vulnerable to earthquake damage, especially large-magnitude megathrust events, due to the unique seismic profile of the region. However, the size of the Western Interconnection makes it difficult to model seismic failure in electrical substations to the level of detail necessary to improve...

  • Low-voltage pipeline A/D converter

    Creator:
    Wu, Lei
    Abstract:
    Continuous process scale-down and emerging markets for low-power/low-voltage mobile systems call for low-voltage analog integrated circuits. Switched-capacitor (SC) circuits are the building blocks for analog signal processing and will encounter severe overdrive problems when operating at low voltage conditions. There exist three techniques to solve the problem, but with their...

  • Design and Implementation of a Ride-On Car with Data Tracking for Use by Young Children with Developmental Differences

    Creator:
    Brian, Makenzie M.
    Abstract:
    This work describes the design and modification of a commercial children’s ride-on car to effectively collect usage data. The design is cheap and could be easily modified to gather more information. This will serve as a viable way to collect information about how motorized independence can help children with developmental...

  • Enhanced inverse synthetic aperture radar imagery using 2-D spectral estimation

    Creator:
    Ohm, David R.
    Abstract:
    This research focused on the use of classical and modern two-dimensional spectral estimation techniques for enhancing inverse synthetic aperture radar (ISAR) imagery. 2-D Classical spectral estimation methods and 2-D modern parametric and non-parametric spectral estimation methods are applied to simulated and real data sets in order to achieve both range...

  • Low power, high performance pseudo-static D flip-flop

    Creator:
    Low, Tim D.
    Abstract:
    Digital systems, in particular microprocessor, have recently experienced phenomena growth in performance. Both technology advancement and clever design have sustained this performance growth. As clock frequency heads into the Ghz range, new circuit design, for both logic and storage, are needed. Such new circuit technology must provide needed performance with...

  • Analysis and design of bandpass delta-sigma A/D converters

    Creator:
    Zhai, Dalun
    Abstract:
    A new approach to oversampled delta-sigma A/D converters ( AZ modulators ) is introduced, where a differential pseudo-Npath filter stage is used as a basic cell. In this band-pass application, the z to -zN transformation is employed to realize a RAM-type pseudo-2-path lossless integrator. The bandpass second-order and 4th-order delta-sigma...

  • Area efficient D/A converters for accurate DC operation

    Creator:
    Greenley, Brandon Royce
    Abstract:
    The design of mixed-signal integrated circuits has evolved from simple analog and digital circuits operating on the same silicon substrate to the point that now we have complete system on a chip solutions for communication systems. The levels of integration needed to remain cost effective in today's integrated circuit (IC)...

  • Adaptive correction techniques for delta-sigma A/D converters

    Creator:
    Abdennadher, Salem
    Abstract:
    Oversampling analog-to-digital and digital-to-analog converters are gaining more popularity in many signal processing applications. Delta-sigma modulators are used in practical applications of oversampling systems because of their apparent practical advantage over other oversampling converters in terms of insensitivity to the inevitable imperfection of the analog circuitry. In Δ∑ modulators, analog...
