Inductive power transmission and distribution apparatus using a coaxial transformer

An inductive power transfer apparatus for transferring power from a power source comprising:

• a primary conductor having a longitudinal axis, the primary conductor extending in the longitudinal direction, the primary conductor having a first end and a second end;
• a return conductor surrounding the primary conductor and spaced apart therefrom;
• a first support element configured and arranged to secure the center conductor in place;
• the primary conductor electrically coupled to the power source and receiving power therefrom and the primary conductor further electrically coupled to the return conductor, the return conductor being electrically coupled to the power source to provide a return path thereto;
• a moveable secondary winding including a high permeability toroidal core coaxially disposed about the center conductor and spaced apart therefrom forming a first air gap, the toroidal core including a second air gap, the first support element disposed within the second air gap, the secondary winding further including a multi-turn coil disposed radially about a portion of the high permeability toroidal core;
• a second support element configured and arranged to support the high permeability core and the multi-turn coil;
• and
• whereby an alternating current imposed upon the primary conductor by the power source generates a magnetic field that is magnetically coupled to the multi-turn coil and induces a voltage therein.
