  1. 1191. M4Or1A-01 [Invited]: Recent Developments at NASA Glenn towards a Fully Superconducting Electric Machine
    Jason Hartwig (NASA Glenn Research Center)
    25/07/2019, 09:30
    Invited Oral Presentation

    This presentation discusses recent research and technology development at the NASA Glenn Research Center on superconducting electric machines. Specifically, the presentation will discuss the design, development, operation, and test capabilities of a superconducting coil testbed to measure alternating current (AC) losses for both low- and high-Tc superconductors. AC losses are important in the...

  2. 699. M4Or1A-02 [Invited]: Dynamic and Static Characteristics of Press Pack IGBT at RT and 77 K
    Chanyeop Park (Georgia Tech)
    25/07/2019, 10:00
    Invited Oral Presentation

    Superconducting power systems, a promising technology for electric aircraft and all-electric ships, are expected to have many power conversion stages among generators, transmission cables, storage devices, and loads. However, the current technology does not allow power conversion stages to be operated at cryogenic conditions. The lack of such technology deteriorates the overall system...

  3. 714. M4Or1A-03: Electrical Performance of Cryogenic Inductors
    Chanyeop Park (Georgia Tech)
    25/07/2019, 10:30
    Contributed Oral Presentation

    Inductors typically consist of copper or aluminum windings around magnetic cores. However, as magnetic cores are not suitable for cryogenic applications due to substantial eddy current loss generated by reduced core resistivity at cryogenic conditions, coreless inductor designs are preferred for cryogenic applications.

    In this paper, we report the electrical performance including ampacity...

  4. 1037. M4Or1A-04: Understanding Surface Flashover in Helium Gas Cooled High Temperature Superconducting Devices
    Mr Aws Al-Taie (Florida State University)
    25/07/2019, 10:45
    Contributed Oral Presentation

    High temperature superconducting (HTS) devices enable high current densities to be achieved. For some applications the required operating temperature is less than 50 K and gaseous helium (GHe) is utilized as the cryogen instead of the commonly used liquid nitrogen. These applications include devices with MgB2 as the superconductor, and for HTS motors, generators and, magnets which operate with...

  5. 1066. M4Or1A-05 [Invited]: Development of Superconducting-Magnetic-Energy-Storage (SMES) for Electric Aircraft Propulsion
    Timothy Haugan (U.S. Air Force Research Laboratory)
    25/07/2019, 11:00
    Invited Oral Presentation

    Electrical energy storage devices are critical components of electric power systems of every aerospace vehicle. They are needed for many functions, such as an energy source for electric-vehicle (EV) propulsion, as an electrical accumulator unit (EAU) to handle 2-3x higher-than-average transient loads both on/off the power buses, for emergency power during system failure, and to provide...
