Abstract
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.
Claims20
An electrical coil of at least two turns, comprising:
- a first electrically-conductive element of a thin, flat, annular configuration formed with a gap to define a first turn of the coil;
- a second electrically-conductive element also of a thin, flat, annular configuration and also formed with a gap to define a second turn of the coil, said second electrically-conductive element being disposed coaxially with respect to said first electrically-conductive element;
- and electrical insulation between said first and second electrically-conductive elements insulating said first turn from said second turn except for one end of each turn to be electrically connected together;
- characterized in that said insulation includes an electrically-insulative element also of a thin, flat, annular configuration disposed coaxially between said first and second electrically-conductive elements and formed with a gap aligned with said one end of each turn to permit said ends to be electrically connected together.
A transformer winding including a spool carrying two coils each produced by winding an insulated electrical conductor from a mid-portion thereof such that the produced two coils are connected together at said mid-portion, and rotating one coil 180° with respect to the other, when applied to said spool, such as to produce a current flow in the same direction in both coils.
A method of making a transformer, comprising:
- winding an insulated electrical conductor from a mid-portion thereof to produce two coils connected together at said mid-portion;
- rotating one coil 180° with respect to the other;
- and applying the two coils to the spool, such as to produce a current flow in the same direction in both coils when connected to a voltage source.
