Document Type and Number:
WIPO Patent Application WO/2010/024153
Kind Code:
A1
Abstract:
Provided is a three-phase high frequency transformer including: a ferrite core having three columnar cores, a top plate, and a bottom plate; and a three-phase coil having a primary coil of a predetermined internal diameter formed by bending a flat wire in the width direction of the flat wire by a plurality of times and a secondary coil of the same internal diameter as the primary coil formed by bending a flat wire having a different width from the aforementioned flat wire in the width direction of the flat wire, wherein the flat wire constituting the secondary coil is arranged at an interval of the flat wire constituting the primary coil in such a manner that the primary coil and the secondary coil have the same inner circumference and the aforementioned columnar cores are inserted into each of the coils, thereby arranging three sets of coils. The primary coil is connected to the secondary coil by the Δ–connection or the Y-connection.
