Measurement of AC current distributions in HTS tapes
Physica C: Superconductivity, 2008It is important to evaluate the characteristics of the current distributions in the HTS tapes and conductors in order to realize HTS power devices. In this study, we have developed a simple measurement method to evaluate the current distributions in HTS tapes.

Levitation Force of Magnetized HTS Tape Stacks
IEEE Transactions on Applied Superconductivity, 2017High-temperature superconductors (HTS) have the significant potential of magnetic-force-based applications. Nowadays, wide spread of coated conductors tapes (CC-tapes) enables the use of HTS stacks in levitation applications. For the development of CC-tapes-based bearings and transportation systems, it is important to have information on stability of ...

The Levitation Force Characteristics of Stacked HTS Tapes
2020 IEEE International Conference on Applied Superconductivity and Electromagnetic Devices (ASEMD), 2020High temperature superconducting (HTS) tapes can be stacked into a block structure and be used in HTS magnetic levitation systems. This paper proposes a simulation method based on H-formulation to study the levitation force characteristics of the stacked HTS tapes on the permanent magnet guideways (PMG) in Comsol Multiphysics.

Reduction of Magnetization in Windings Composed of HTS Tapes
IEEE Transactions on Applied Superconductivity, 2012Methods to reduce the magnetization in windings composed of high temperature superconductor (HTS) tapes are presented on the basis of the abnormal transverse-field effect. The toroidal arrangement as well as the coaxial arrangement of additional coils wound with non-magnetic wires such as copper wires is effective to uniformize the distribution of ...

Design of HTS Tape Characteristics Measurement System
IEEE Transactions on Appiled Superconductivity, 2004High temperature superconductor (HTS) tapes are now commercially available for practical applications to apply various purposes. However HTS tapes show different electrical and mechanical characteristics, according to the manufacturers who are trying to apply various fabrication processes and treatments. From the viewpoint of an application, it is very

Stresses and strains in multi-filament HTS tapes
IEEE Transactions on Appiled Superconductivity, 1999High temperature superconducting tapes are now commercially available for practical applications such as magnets and cables. However, still today the published data on strength and allowable deformation limits of these tapes are not altogether in agreement. Definitions and concepts with regards to the stresses and strains in HTS tapes under deformation

Characteristic Analysis of HTS Linear Synchronous Generators Designed With HTS Bulks and Tapes
IEEE Transactions on Applied Superconductivity, 2014Two types of high temperature superconducting (HTS) linear synchronous generators (LSG) have been analyzed, which models developed have either an HTS bulk magnet array or an HTS tape coil as their secondary mover. The no-load induced voltage and output power characteristics versus the trapped flux density of the HTS bulk magnets, the HTS tape coils ...
