PLANAR TRANSFORMER, METHOD FOR PRODUCING WINDING WIRE THEREFOR AND COMPACT ELECTRICAL DEVICE PROVIDED THEREWITH

摘要

PROBLEM TO BE SOLVED: To easily and inexpensively produce a planar transformer with an arbitrary number of winding wires by improving the type composed of at least one primary winding wire, at least one secondary winding wire and a transformer core. ;SOLUTION: This transformer is composed of a folded conductor 15, with which a primary winding wire 3a and a secondary winding wire 3b respectively have non-round lateral cross sections.;COPYRIGHT: (C)2001,JPO
