  • Transformer
    Patent number: 8928446
    Abstract: An electromagnetic shield includes a plurality of magnetic thin plates stacked on each other, a pair of metal plates sandwiching the plurality of magnetic thin plates, and a plurality of seat plates each connected to the pair of metal plates. The plurality of seat plates are disposed at positions where the total sum of a leakage flux interlinked with a region between mutually adjacent first and second seat plates among the plurality of seat plates is equal to zero. Preferably, a distance between the first and second seat plates is equal to a value which is an integral multiple of a half period of the distribution of the leakage flux.
