  • 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...

  • Investigation and comparison of generators for dynamic operation in ocean buoys

    Creator:
    Schacher, Anthony Clinton
    Abstract:
    A significantly untapped renewable energy source exists in the world's oceans. It is estimated that if 0.2% of the ocean's untapped energy could be harnessed, it could provide power sufficient for the entire world. Ocean energy extraction is an old concept, and it is currently seeing the benefit of advancing...

  • Detection of incipient rotor bar faults and air-gap asymmetries in squirrel-cage motors using stator current monitoring

    Creator:
    Al Tuaimi, Hamad A.
    Abstract:
    Preventative motor fault detection is of prime importance for modern plant management. During research into rotor faults, performed at the Motor Systems Resource Facility (MSRF), an optimized rotor fault detection and classification method was proposed. In critical process applications, the suggested method would provide the foundation for continually monitoring a...

  • 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...

  • A direct-drive wave energy converter with contactless force transmission system

    Creator:
    Agamloh, Emmanuel B.
    Abstract:
    Commonly proposed ocean wave energy converters (OWEC) use inefficient and maintenance demanding intermediate hydraulic and pneumatic systems. We propose a novel rotary direct-drive OWEC that eliminates these intermediate stages. The new device employs a contactless force transmission system (CFTS) comprising a “piston” and a “cylinder” and a ball screw to...

  • Electromagnetic analysis of energy system devices

    Creator:
    Li, Yan
    Abstract:
    Many new applications of energy system devices have been developed to save energy, improve the controllability and stability of industrial processes, and reduce the weight, volume and cost of consumer devices. Due to the novelty of these devices, traditional empirical methods and lumped-parameter circuit theory methods are not sufficient for...

  • Influence of adjustable speed drive on induction motor fault detection using stator current monitoring.

    Creator:
    Al-Shahrani, Ali
    Abstract:
    The detection of motor faults at their incipient stage is of prime importance to any industrial plant. The introduction of adjustable speed drives has improved the control and the efficiency of induction motors, however, this has changed the nature of motor faults and how they can be detected. Current signature...

  • Evaluation of partial discharge in inverter driven medium voltage propulsion coils

    Creator:
    Ramme, André
    Abstract:
    Advancements in power electronics to higher power levels and faster switching times allow new machine and systems designs, but also create higher stresses on electric machinery insulation. High performance, pulse-width modulated (PWM) inverters are now available for medium voltage drive systems, and are being considered by the U.S. Navy as...

  • Active power filter for the cancellation of harmonic line current distortion

    Creator:
    Merk, Marcel
    Abstract:
    With the increased attention on high efficiency and energy savings, power electronic energy conversion equipment is increasingly incorporated in all levels of the power system. The drawback of such equipment is the generation of nonsinusoidal currents in the power distribution network due to the nonlinear operation. Harmonic currents may distort...

  • Power quality simulator for commercial office buildings

    Creator:
    Atluri, Prabha Krishna
    Abstract:
    The distortions of input voltage and current waveforms generated by switch mode power supply (SMPS) operation are a major cause of concern in the power quality performance of commercial office buildings. These distortions are usually evaluated by performing a site survey of the building. In this thesis, a power quality...
