US 2011/0090038 A1 · TRANSFORMER HAVING INTERLEAVED WINDINGS AND METHOD OF MANUFACTURE OF SAME

Abstract

A transformer may include a first and a second continuous single piece multi-turn helical winding where at least some turns of the windings are interleaved. The turns of the windings are electrically insulated from one another and spaced sufficiently close together to permit inductive coupling therebetween. The single piece multi-turn helical windings may have a continuous or smooth radius of curvature, with no discontinuities or singularities between first and second end terminals. The transformer may be formed by wrapping first and second electrical conductors about a winding form to form the first and second continuous single piece multi-turn helical windings substantially concurrently. Alternatively, a second continuous single piece multi-turn helical winding may be advanced on a first continuous single piece multi-turn helical winding, for example by rotation with respect thereto.

Dependent claims

A transformer, comprising:

a first continuous single piece multi-turn helical winding having a continuous smooth radius of curvature with no discontinuities between a first terminal and a second terminal as projected on an X-Y plane that is perpendicular to a longitudinal axis of the first continuous single piece multi-turn helical winding;
and
a second continuous single piece multi-turn helical winding having a continuous radius of curvature with no discontinuities between a first terminal and a second terminal as projected on an X-Y plane that is perpendicular to a longitudinal axis of the second continuous single piece multi-turn helical winding, the second continuous single piece multi-turn helical winding electrically insulated from the first continuous single piece multi-turn helical winding and having at least some of a plurality of successive turns of the second continuous single piece multi-turn helical winding interleaved between respective pairs of at least some of a plurality of successive turns of the first continuous single piece multi-turn helical winding to inductively couple therebetween.
