Title:
WIRELESS POWER FEEDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/075498
Kind Code:
A1
Abstract:
A power transmission device 31 of a wireless power feeding device 30 includes: a power transmission coil 34; a support base 32 that supports the power transmission coil 34 in a rotatable manner; an actuator 36; a power feeding unit 35 that feeds power to the power transmission coil 34; and a power feeding control unit 37 that adjusts the rotation angle of the power transmission coil 34 by controlling the actuator 36. Each power receiving device 40A, 40B of the wireless power feeding device 30 comprises a power receiving coil 41. The power feeding control unit 37 varies the rotation angle of the power transmission coil 34 when an induced voltage is generated at the power receiving coil 41 of the first power receiving device 40A and when an induced voltage is generated at the power receiving coil 41 of the second power receiving device 40B.
