Patent ID: 7318270

Claim:
A method for producing a full wave bridge rectifier suitable for low-voltage, high-current operation by simultaneously winding a plurality of essentially identical secondary coil sections around a primary coil, the method comprising: winding a primary coil of a given diameter comprised of a thin foil conductor having a width sufficient to encompass the subsequently wound plurality of secondary coil sections side-by-side; preparing a secondary winding ensemble having a plurality of secondary coil sections by laying out a sheet of insulation approximately the width of said primary coil and of a length determined by the diameter of said primary coil and by the number of turns of said ensemble about said primary coil, laying out a plurality of foil conductors parallel to each other and insulated from each other on said insulation sheet, each foil conductor having a start end and a finish end with said start ends being electrically connected by a cross-connection tab, said tab being extended beyond said insulation sheet to thereby form a tab terminal for the start ends of all of the secondary coil sections and said finish ends extending beyond said insulation sheet to become the finish tabs of each secondary coil section; and winding said secondary winding ensemble a predetermined number of times around said primary coil.
