Magnetization Loss in HTS Stacked Tapes by Various Directional External Magnetic Fields

Reduction Effect on Magnetization Loss in the Stacked Conductor With Striated and Transposed YBCC Coated Conductor

“…For large power application using HTS tape, the stacked conductor packing a number of HTS tapes should be used because the current carrying capacity of a single conductor is limited. The stacked conductor has different AC loss characteristics from single tape because the screening currents in the adjacent tapes affect the local magnetic field at the position of each tape in the stacked conductor [3]- [6]. Manuscript The magnetization loss in perpendicular external magnetic field is the main component of AC losses of the YBCO coated conductor in power application.…”

Magnetization Loss and Shield Effect in Multi-Stacked Tapes With Various Stacking Configurations

“…if (4) if (5) When the electric field and the current density distribution are calculated, the Magnetization loss per unit volume per cycle in HTS sample can be expressed as follows.…”

“…In the coil application, the tapes are arranged in several types of stacking configuration such as face-to-face, edge-to-edge, regular matrix and irregular Manuscript matrix type. In our previous study, we reported about the influence of the stacking number and the external magnetic field direction on the magnetization loss of face-to-face stacked conductors with several insulation thicknesses between tapes [4], [5]. In this paper, we research the effect of the stacking configurations mentioned above for magnetization loss in perpendicular magnetic fields.…”

Role of asymmetric critical current on magnetization loss characteristics of (RE)Ba2Cu3O7−d coated conductors at various temperatures

“…Therefore, it is important to investigate the influence of asymmetric I c (B, θ) on magnetization loss of the coated conductors at various operating temperatures. There have been intensive studies on the magnetization loss of HTS coated conductors with various field-angles at 77 K [14][15][16][17][18][19][20][21] and the temperature dependence of magnetization loss under a perpendicular applied magnetic field. [22][23][24] In the field-angle dependence studies, the field angle was varied within 90 at 77 K 14,15 in the experimental studies, and symmetric I c (B, θ) characteristics were assumed in the numerical calculations.…”
