ABSTRACT:
An elongated ferromagnetic core is surrounded by two windings. Optional separators separate the core from the windings and one winding from the other winding. A tube-like ferromagnetic sheath covers the windings and core. The sheath and core are connected, preferably at both ends. At one end, one winding may be connected to a plug for connecting to a wall outlet for supplying an alternating current thereto. At the other end, the other winding may be connected to an external load for providing a voltage thereto. Optionally, an electrically insulating, thermally conductive, outer cover covers the ferromagnetic sheath. In a first embodiment, one winding is surrounded by the other winding. In a second embodiment, one winding surrounds a portion of the core and the other winding surrounds another portion of the core.
