Coupling electromagnetic numerical models of HTS coils to electrical circuits: multi-scale and homogeneous methodologies using the T-A formulation
TL;DR: In this paper , a finite element method-based model coupling the T-A formulation with an electrical circuit has been proposed: the model presents the superconducting constituent as a global voltage parameter in the electrical circuit.
Journal ArticleDOI
Oscillation Characteristics of Levitation Force of YBCO Bulk Exposed to AC Magnetic Field above NdFeB Guideway
TL;DR: In this paper, the effect of the amplitude of the AC magnetic field on the levitation force is studied; the result shows that the oscillation amplitude of a HTS mass increases with the amplitude external magnetic field and is independent of the Field Cooling Height (FCH).
Journal ArticleDOI
Thermo-electromagnetic modeling of coated superconductor coils with metal insulation
TL;DR: In this article, the authors developed a thermo-electromagnetic model to theoretically understand and predict the properties of the metal-insulation coils, in which a modified equivalent circuit for electrically representing the metal insulation coils is built to take the effect of insulator into account.
Journal ArticleDOI
Numerical Evaluation of Levitation Force Oscillation of HTS Bulk Exposed to AC Magnetic Field over NdFeB Guideway
TL;DR: In this article, an analytical model is adopted to evaluate the levitation force of YBCO bulk over an NdFeB guideway used in the high-temperature superconducting (HTS) maglev vehicle system is oscillated by the application of the AC external magnetic field.
