WIRELESS POWER TRANSFER SYSTEM, POWER RECEIVER, AND WIRELESS POWER TRANSFER METHOD

摘要

A power receiver includes a resonance coil, an oscillation unit, a communication unit, and a control unit. The resonance coil is configured to wirelessly receive power from a power source using magnetic field resonance or electric field resonance, the oscillation unit is configured to output a voltage which oscillates at a predetermined frequency, and the communication unit is configured to communicate with the power source. The control unit is configured to receive an output from the communication unit, and adjust a resonance frequency of the resonance coil using an output voltage from the oscillation unit.
