Title:
WIRELESS POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/229841
Kind Code:
A1
Abstract:
The present invention comprises: a power receiving resonance circuit including a first coil to which power is transmitted by using resonance of a magnetic field, a first capacitor connected to the first coil, a load detection unit that acquires load information related to a load connected to the first coil, and a first communication unit that transmits the load information; and a power transmitting resonance circuit including a second coil that transmits the power to the first coil by using the resonance of the magnetic field, a second capacitor connected to the second coil, a second communication unit that receives the load information transmitted from the first communication unit, and a determination unit that determines an electrostatic capacitance of the first capacitor and/or the second capacitor on the basis of the load information so as to have the greatest power transmission efficiency with the power receiving resonance circuit.
