Abstract
Described herein are embodiments of a wireless power receiver that includes a receive high-Q resonator configured to receive wireless power from a magnetic near field, the receive high-Q resonator that may include a first resonator and a second resonator wirelessly coupled to the first resonator. The wireless power receiver may be included in a non-contact power transmission apparatus that includes a resonance system, which may include a primary coil to which an oscillating voltage from a source is applied, a primary-side resonance coil, a secondary-side resonance coil, and a secondary coil to which a load is connected, wherein the impedance of the primary coil is set such that the output impedance of the oscillating source and the input impedance of the resonance system are matched to each other.
