Magnetization Losses of the HTS Stacked Tapes at Various Gap between Tapes

Rise of the current level at power applications, such as, transformer, motor and power cable, need for using stacked HTS tapes. In this paper, we measured losses of the stacked HTS tapes. Three different types of the stacks which were made of 2 tapes, 3 tapes and 4 tapes, were tested Perpendicular magnetic field was applied to the HTS stacks as the external magnetic field. Effects of the gap between HTS tapes were examined.
