    摘要： An electric transformer comprising a coil made of at least one winding (42), the winding (42) being made of a wire comprising a first section (51), a second section (52) and a middle section (55) between the first and the second sections, the first section forming a first spiral around an axis (Z) and the second section forming a second spiral around the axis, the first and second spirals being located in two separate planes (P1, P2) perpendicular to the axis, an inner end (53, 54) of the first spiral, respectively the second spiral, located near the axis being near the middle section (55) of the winding and an outer end (58, 57) of the first spiral, respectively the second spiral, located away from the axis being near a free end of the winding, the first spiral and the second spiral turning around the axis in opposite directions (F1, F2).

    摘要： In accordance with one embodiment is a transformer with a core comprising a perimeter portion and central intervening portion. The central intervening portion is separated from the perimeter portion by air gaps, creating an opening on either side of the intervening portion. A primary winding and secondary winding are wound around the central intervening portion of the core. The primary winding is capable of electromagnetic interaction with the secondary winding. A pair of ferrite members arranged outward from a central axis of the central intervening portion of the core and increases a series inductance with the primary winding. In accordance with another aspect of the disclosure, each ferrite member may have an air gap associated with the core to facilitate heat dissipation from the transformer.

    摘要： A filter assembly includes a first self-inductance core, a second self-inductance core, a coupled inductor core, and a first plurality of inductor coil windings. Each of the first plurality of inductor coil windings has a series of first turns in a vertically stacked relation around the first self-inductance core, and a series of second turns in a vertically stacked relation around the first self-inductance core and the coupled inductor core. The filter assembly further includes a second plurality of inductor coil windings. Each of the second plurality of inductor coil windings has a series of first turns in a vertically stacked relation around the second self-inductance core, and a series of second turns in a vertically stacked relation around the second self-inductance core and the coupled inductor core.

    摘要： A shunt reactor comprising a primary winding (1) and a steel core (2) is presented. The steel core comprises a bottom yoke (3), a top yoke (4), a first core limb (5), a second core limb (6), and a main limb (7). The first core limb, the second core limb and the main limb are arranged in parallel and in between the top yoke and the bottom yoke to form a support for a magnetic flux through the steel core. The primary winding is wound around the main limb to generate the magnetic flux through the steel core. The shunt reactor further comprises an auxiliary winding (8; 8') arranged wound around the bottom yoke, top yoke, first core limb, or second core limb, and is configured to generate auxiliary power from the magnetic flux generated by the primary winding. The primary and the auxiliary windings are electrically insulated from the steel core and from each other.
