Summary:In this paper, AC transport current loss of vertically (face-to-face) stacked HTS tapes is evaluated through numerical, analytical methods and experimental measurement as well. Single, two- and three-stacked tapes were fabricated and AC transport current losses were measured electrically. Numerical calculation, which uses electric scalar and magnetic vector potentials as unknowns, was also performed and it was confirmed that the numerically calculated losses coincide excellently with the measured ones. Two other analytical methods, which are basically from the Norris ellipse equation using degraded critical current, are proposed and the comparison of the loss data is addressed.
