Analytical model for AC losses in HTS tapes

This model was shared by João Fernandes, Instituto Superior Técnico, Ulisboa.

This work proposes two alternative analytical models to evaluate the AC losses of High-Temperature Superconducting (HTS) tapes during their hysteretic and resistive modes. Two analytical models are proposed, one considering an extension of the Norris model for the HTS tape’s resistive mode and the other based on a Sigmoid function to characterize the hysteretic losses and their smooth transition to the resistive mode. It is intended to help electromechanical systems designers to estimate the losses of HTS tapes during the design stage.
