Abstract
A resonant power transmission system for wirelessly delivering electric power to a target device. A transmitter resonant phased array includes a power source operable to source alternating current power at a target frequency. A plurality of transmitting elements, each operable to produce a non-radiated magnetic field, produces a composite non-radiated magnetic field. A plurality of transmitter tuned circuit elements couple the alternating current power to the plurality of transmitting elements. Control circuitry controls the plurality of transmitter tuned circuit elements to direct the composite non-radiated magnetic field toward the target device. Communication circuitry communicates with the target device. The plurality of transmitting elements may be a plurality of coils with the control circuitry individually controlling phase of the non-radiated magnetic fields produced by the plurality of transmitting elements by control of the plurality of transmitter tuned circuit elements. The plurality of coils may be directed mechanically in other embodiments.
