Hybrid coil for wireless power transfer

A method for constructing a wireless power apparatus, the method comprising:

• forming a first conductor assembly having a first conductor type;
• forming a second conductor assembly having a second conductor type that is different from the first conductor type;
• and
• connecting the first conductor assembly and the second conductor assembly in series to form a receiver coil as a hybrid coil.

A wireless power system, comprising:

• an alternating current power source configured to provide electrical power;
• a power transmitter having a transmitter coil being wound circularly around a center point and disposed in a first plane to form a planar transmitter coil, the planar transmitter coil configured to be connected to the alternating current power source to wirelessly transmit power;
• a power receiver with a receiver coil having a first conductor assembly with a first conductor type, the receiver coil having a second conductor assembly with a second conductor type that is different from the first conductor type, the first conductor assembly and the second conductor assembly being connected in series to form a hybrid coil, the first conductor assembly being an inner winding and the second conductor assembly being an outer winding, the inner winding being wound circularly around a center point in a second plane, the outer winding being wound around the inner winding in the second plane to form a planar hybrid receiver coil, the power receiver configured to receive power from the planar transmitter coil when the planar hybrid receiver coil is in proximity to the planar transmitter coil;
• and
• a load configured to receive power from the power receiver.
