Abstract
A new resonance-based wireless power transfer system is disclosed. The new resonance-based wireless power transfer system includes a power transmitter and a power receiver. The power transmitter and the power receiver are both oscillator-based circuits, but unlike prior systems, their resonant frequencies are different. The difference between the transmitter's resonant frequency and the receiver's resonant frequency is set between a lower bound and an upper bound to ensure that the new resonance-based wireless power transfer system will have only one oscillation frequency while maintaining high power transfer efficiency over varied distances.
