Abstract:
1. A high power wireless resonant energy transfer system, comprising: an energy transmission system arranged to wirelessly transfer energy across an airgap, wherein said energy transmission system comprises at least one pair of primary resonant circuits, each one of said at least one pair arranged to inductively couple with another of said at least one pair by an inductive coupling to establish a common resonant frequency for said at least one pair of primary resonant circuits; and an energy reception system positioned to receive said transferred energy across said airgap through a resonant inductive coupling between said transmission and said reception system, said energy transmission system arranged to automatically and electronically vary the spatial direction of said resonant inductive coupling with the alignment between said transmission and reception system, such that energy transfer occurs at a desired location, frequency and power level.
