Static and Transient Characteristics of Hybrid HTS Coils
This paper presents some transient and static characteristics of hybrid high temperature superconducting (HTS) flat coil prototypes. Two HTS coil prototypes were designed using 3D CAD software for working in hybrid HTS system consisting of superconducting part (in cold condition) and nonsuperconducting part (in warm condition). The coils consist of HTS flat composite wires with superconducting layer of GdBCO. Inductance of the created coils was calculated using existing analytical formulas and measured experimentally in warm and cold (superconducting) state. Theoretically, calculated inductance was compared with measured values. Critical temperature and resistance were measured during the transition from superconducting to nonsuperconducting state. A design for coreless superconducting transformer was proposed and tested. This design is suitable for superconducting wireless power transfer with very high efficiency.
