ELECTRIC POWER CONVERSION APPARATUS, CURRENT-CARRYING DEVICE THAT CARRIES AC POWER, AND METHOD OF MANUFACTURING CURRENT-CARRYING DEVICE THAT CARRIES AC POWER

摘要

A current-carrying device that carries AC power, including: an adjacent portion in which the AC power is input from or output to an external device; and a fuse portion that is adjacent to the adjacent portion, in which a cross-sectional area of the fuse portion is smaller than that of the adjacent portion, and in which a magnetic flux density generated in the fuse portion is smaller than a magnetic flux density generated in the adjacent portion when a structure of the fuse portion is made identical with that of the adjacent portion.
