<P>PROBLEM TO BE SOLVED: To provide a coil and a method of winding coil wires that achieve effective use of winding space by outer revolute winding of coil wires, and minimize the normal mode inductance. <P>SOLUTION: The coil 10 has a core 12, two wires 18A, 18B wound on the core 12, and flanges 14, 16 which are installed on both ends of the core 12 with the mutually spaced size approximately two times the diameter of the wires 18A, 18B. The two wires 18A, 18B are wound mutually in the opposite direction along the surface of the core 12 when the wires 18A, 18B are arranged along the axis direction of the core 12, thereby magnetic fluxes generated by currents flowing in the adjacent wires 18A, 18B when the wires 18A, 18B are wound on the core 12 are mutually cancelled. <P>COPYRIGHT: (C)2009,JPO&INPIT |
