Title:
WIRELESS POWER-FEEDING DEVICE, WIRELESS POWER-FEEDING SYSTEM, AND WIRELESS POWER-FEEDING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/129247
Kind Code:
A1
Abstract:
This invention discloses a wireless power-feeding device and the like that allow stable wireless power feeding, even in underwater environments and the like, including in seawater. Said wireless power-feeding device (100) has a power-transmitting unit (3) that wirelessly transmits electric power through a good-conductor medium (5), a power-receiving unit (4) that receives the wireless power transmitted by the power-transmitting unit (3), and a system control unit (2) that controls the power-transmitting unit (3) and the power-receiving unit (4). The system control unit (2) transfers electric power via resonance at a frequency determined by the impedance of the power-transmitting unit (3), the impedance of the power-receiving unit (4), and the impedance of the good-conductor medium (5) while regulating the phase thereof.
