WIRELESS POWER APPARATUS AND METHODS

摘要

PROBLEM TO BE SOLVED: To provide techniques of maintaining high-Q resonance matching so that antennas maintain resonance with high Q in a wireless energy transfer system.

SOLUTION: An apparatus for supplying power to a load through at least one wireless field comprises: a first antenna circuit configured to receive power from a voltage source through a first wireless field at a first power level corresponding to a voltage signal varying over time; and a second antenna circuit configured to output power at a second power level to supply power to the load through a second wireless field.
