Abstract

The hysteretic ac loss of a current-carrying conductor in which multiple superconducting strips are polygonally arranged around a cylindrical former is theoretically investigated as a model of superconducting cables. Using the critical state model, we analytically derive the ac loss Qn of a total of n strips. The normalized loss Qn Q1 is determined by the number of strips n and the ratio of the strip width 2w to the diameter 2R of the cylindrical former. When n1 and wR1, the behavior of Qn is similar to that of an infinite array of coplanar strips.
