Modeling of High Temperature Superconducting Stacks Under T-A Formulation

In this paper, we first established an efficient HTS stack model using the finite element method (FEM). The model used to determine the electromagnetic characteristics of stacks composed of second-generation high temperature superconductors (HTS) is based on the two-dimensional T-A formulation. The magnetic vector potential A is solved using an effective method that differs from the prior integral method, and the superconducting layer is built as a one-dimensional model. Finally, the results show that the suggested method is accurate and effective in terms of the distribution of magnetic fields, current densities, and AC loss.
