Title:
WIRELESS POWER RELAY DEVICE AND WIRELESS POWER TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/167055
Kind Code:
A1
Abstract:
The present invention can prevent a sudden deterioration of transmission efficiency of a wireless power relay device having a plurality of relay coils by arranging a relay coil having higher transmission efficiency than that of the other relay coils in a section with low transmission efficiency. More specifically, the present invention provides the wireless power relay device, which has a plurality of relay coils for capturing and relaying a magnetic field, wherein if a transmission efficiency-reducing section, in which the transmission efficiency of a first relay coil spaced from a wireless power transmission device among the relay coils is lower than the transmission efficiency of a second relay coil neighboring the first relay coil and arranged farther than the first relay coil, is generated, at least one relay coil arranged in the transmission efficiency-reducing section among the plurality of relay coils relay a magnetic field differently from a phase of the magnetic field relayed by the other relay coils.
