Title:
LAMINATED MAGNETIC COMPONENT
Document Type and Number:
WIPO Patent Application WO/2005/031765
Kind Code:
A1
Abstract:
A laminated transformer (10) comprising a plurality of laminated magnetic sheets (11a-11i), through holes (12a-12d) made through the magnetic sheets (11b-11i), laminating-direction wirings (13a-13d) consisting of conductors and filling the through holes (12a-12d), wirings (14a-14d) formed on the planes of the magnetic sheets (11b, 11c, 11f, 11g), in the planar direction, a secondary wiring (15) consisting of the planar-direction wiring (14a, 14d) and the laminating-direction wirings (13a, 13d), and a primary winding (16) consisting of the planar-direction wiring (14b, 14c) and the laminating-direction wirings (13b, 13c). Allowable current capacity of the winding is substantially proportional to the cross-sectional area of the conductor of the winding. Since the cross-sectional areas of the conductors of the laminating-direction wirings (13a-13d) equal the areas of the through holes (12a-12d), the capacity can be increased as much as one likes.
