Abstract

PURPOSE:To reduce an increasing of core loss due to a high harmonic wave magnetic flux by wrapping a amorphous magnetic substance around the inner and outer layer portions of a winding core. CONSTITUTION:Around the inner and outer layer portions of a core 2 wherein a silicon steel plate is wrapped in a spiral shape, for example an amorphous magnetic substance 1 of e-B system is wrapped at a thickness equivalent to 15% of the full stacked thickness. According to the constitution, the increasing of the volumn is suppressed at 3% substantially when the core assembly holes the same capacity as that of a core manufactured by only silicon steel plate and but the core loss can be reduced 30% substantially.
