Abstract
An electromagnetic energy harvester circuit to obtain unrealized potential energy employs an E-I inductor having a primary coil winding and a secondary coil winding. A capacitor is electrically coupled to a main power source and upper lead to the primary coil winding, wherein a lower lead of the primary coil winding is coupled to a primary AC load. The secondary coil winding has an upper lead coupled to a first input of a secondary load and a lower lead coupled to a second input of the secondary load. The circuit harvester's electrical current produced through the windings to allow operation of the secondary load.

An electromagnetic circuit for harvesting energy to power a secondary load comprising:
- an E-I inductor having an E laminate and an I laminate defining a center leg spaced apart from two outer legs;
- a primary coil winding having an upper lead winding around a top portion of said center leg with a primary coil winding outlet, said primary coil winding forming magnetic field flux lines that rotate alternately in a clockwise direction and counter-clockwise direction;
- a capacitor electrically coupled to a main power source and said primary coil winding upper lead, wherein a lower lead of said primary coil winding is coupled to a primary AC load;
- a secondary coil winding having an upper lead coupled to a first input of a secondary load and a lower lead coupled to a second input of the secondary load, said secondary coil winding forming a magnetic field flux lines that rotate in a counter-clockwise and clockwise direction.
An electromagnetic circuit comprising:
- an E-I inductor having an E laminate and an I laminate defining a center leg spaced apart from two outer legs, wherein no magnetic attraction exists between the E laminate and the I laminate;
- a primary coil winding having an upper lead winding around a top portion of said center leg with a primary coil winding outlet, said primary coil winding forming magnetic field flux lines that rotate alternately in a clockwise direction and counter-clockwise direction;
- a capacitor electrically coupled to a main power source and said primary coil winding upper lead, wherein a lower lead of said primary coil winding is coupled to a primary AC load;
- a secondary coil winding having an upper lead coupled to a first input of a secondary load and a lower lead coupled to a second input of the secondary load, said secondary coil winding forming a magnetic field flux lines that rotate in a counter-clockwise and clockwise direction;
- wherein the electromagnetic circuit is constructed and arranged to harvest magnetic field energy caused by the flow of alternating electrical current through a conductor to power a secondary load with an electromotive force, or be directed back to a grid without affecting operational characteristics of a primary load.
