A coil form with a low inter-winding capacitance is disclosed including a bobbin formed from an electrically insulating material and including a tube section shaped wall. A coil is mechanically supported by the bobbin and includes a first plurality of conductor windings on the outside of the wall and a second plurality of conductor windings on the inside of the wall. Furthermore, a transformer with such a coil form as any of its primary or secondary windings is disclosed.

Low inter-winding capacitance coil form

An inductor assembly is disclosed that includes a magnetic core with a center leg and a number n of phase legs, wherein n is an integer and n&#x3e;1. Each phase leg is magnetically connected to the center leg by an upper bridge and a lower bridge to form a magnetic main loop, a midpoint of the phase leg being magnetically connected to a center point of the center leg by a shunt element including a gap. Each phase leg further includes an upper inductor coil disposed on an upper phase leg section located between the midpoint and the upper bridge and a lower inductor coil disposed on a lower phase leg section located between the midpoint and the lower bridge. Alternatively, the upper and lower inductor coils are disposed on respective upper and lower bridges.
