Title:
WIRELESS POWER-TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/002126
Kind Code:
A1
Abstract:
The present invention is provided with: a power transmission device (101) which applies an AC voltage to an active electrode (11) and a passive electrode (12); and a power receiving device (201) which supplies, to a load, a voltage induced by capacitively coupling an active electrode (21) facing the active electrode (11), and a passive electrode (22) facing the passive electrode (12). The power transmission device (101) is provided with a planar coil (13) which has a first end connected to the active electrode (11), and a second end connected to the passive electrode (12). The power receiving device (201) is provided with a planar coil (23) which has a first end connected to the active electrode (21), and a second end connected to the passive electrode (22). Magnetic flux generated in the planar coil (23) links to the planar coil (13), and magnetic flux generated in the planar coil (13) links to the planar coil (23), thereby magnetic-field coupling the planar coils (13, 23). As a result, provided is a wireless power-transmission system which is capable of transmitting power efficiently.
