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.

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

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.

Comparison of Overcurrent Responses of 2G HTS Tapes
IEEE Transactions on Applied Superconductivity, 2016In this paper, the comparison of transient responses of second-generation (2G) high-temperature superconducting (HTS) tapes under alternating overcurrent was presented. The authors performed the series of measurements of the SF4050 and SCS4050 HTS tapes produced by Superpower Co.

AC transport current loss in stacked HTS tapes
Physica C: Superconductivity, 2002In general, as we stack HTS tapes, such as Bi-2223, transport AC loss increases more than the single tape loss multiplied by the stacked number. That is due to the AC transport current effects of adjacent/neighboring tapes. To find a way to estimate the AC losses of stacked tapes, we fabricated single-, double- and triple-stacked Bi-2223 tapes, which ...

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 ...

Magnetic Response of the Stacks of HTS Tapes
IEEE Transactions on Applied Superconductivity, 2016We have performed a numerical analysis of the magnetic response of a single piece of a high-temperature superconducting (HTS) tape and the stacks of rectangular pieces of HTS tapes. The number of tapes in the stacks was varied from $N=1$ to 100. We have carried out the simulation in the framework of the critical state model, taking into account ...

Critical Current of the HTS Winding Wound With 12 mm YBCO HTS Tape
IEEE Transactions on Applied Superconductivity, 2013Wide 12-mm high-temperature superconducting (HTS) tapes are being used for HTS windings. The critical current of an HTS winding with a 12-mm HTS tape is calculated in this paper, with consideration of the nonuniform current distribution at the cross-section of the HTS tape.

Optimization of HTS Tape Coil Design
2010HTS tapes are promising materials for RF coil due to their advantages of easier fabrication, easier frequency adjustment and lower cost over HTS films. A theoretical model was developed to investigate the relationship of Q with coil size, solder joint and resonant frequency. The model showed that Q increased with size and frequency.
