An electrical coil includes first and second electrically-conductive elements each of a thin, flat, annular configuration formed with a gap to define the turns of a 2-turn coil, and an electrically insulative element also of a thin, flat, annular configuration disposed coaxially between the two electrically-conductive elements and formed with a gap aligned with one end of each turn to permit the ends to be electrically connected together. Also described is a transformer having a secondary winding including a plurality of such 2-turn coils, and a primary winding of a plurality of double-coils each connected together at their mid-portions.

High-current electrical coil, and transformer construction including same

A high-current electrical coil includes a plurality of flat, electrically-conductive strips bent to define together a coil in which the electrically-conductive strips are disposed coaxially and extend longitudinally with respect to the longitudinal axis of the coil. Each of the electrically-conductive strips is bent to define at least a part of a turn of the coil. One electrically-conductive strip has an outer end carrying a first connector terminal for the coil and projecting outwardly of the coil; and another electrically-conductive strip has an outer end carrying a second connector terminal for the coil and projecting outwardly of the coil. Each of the electrically-conductive strips includes inner ends in electrical continuity with each other, and intermediate portions electrically-insulated from each other such that the plurality of electrically-conductive strips together define a coil exceeding one turn between the first and second connector terminals.
