METHOD FOR MAKING MAGNETICS ASSEMBLY INCLUDING TRANSFORMER

摘要

A method for making a magnetic assembly comprises the following steps: twisting a first to eighth magnetic wires to form a bundle of wires having a first end and an opposite second end; providing a magnetic core; winding the bundle of magnetic wires around the magnetic core; sorting the first end and the second end of the bundle of wires to form individual first ends and individual second ends of the first to eighth wires; picking out the second ends of the first wire and the second wire, and the first ends of the third wire and the fourth wire to form a centre tap of a primary coil of a transformer; and picking out the second ends of the fifth wire and the sixth wire, and the first ends of the seventh wire and the eighth wire to form a centre tap of a secondary coil of the transformer.

1. A method for making a magnetics assembly, comprising the following steps:
(1) providing first to eighth magnetic wires; (2) twisting the first to eighth magnetic wires to form a bundle of wires having a first end and an opposite second end; (3) providing a magnetic core shaped as a toroidal shaft extending along a circle locus around a central axis, the toroidal shaft defining a central opening, a top and a bottom faces perpendicular to the central axis; (4) winding the bundle of magnetic wires around the magnetic core in one direction with the first end extending out from the central opening through the top face of the magnetic core and the second end extending out from the central opening through the bottom face of the magnetic core; (5) sorting the first end and the second end of the bundle of wires to form individual first ends and individual second ends of the first to eighth wires; (6) picking out the second ends of the first wire and the second wire, and the first ends of the third wire and the fourth wire to form a centre tap of a primary coil of a transformer, the first ends of the first wire and the second wire to form an input of the primary coil, and the second ends of the third wire and the fourth wire to form an output of the primary coil; and (7) picking out the second ends of the fifth wire and the sixth wire, and the first ends of the seventh wire and the eighth wire to form a centre tap of a secondary coil of the transformer, the first ends of the fifth wire and the sixth wire to form an input of the secondary coil, and the second ends of the seventh wire and the eighth wire to form an output of the secondary coil.
