WIRELESS POWER RELAY APPARATUS AND WIRELESS POWER TRANSMISSION SYSTEM

摘要

Provided are wireless power relay apparatus and a wireless power transmission system. The wireless power relay system for relaying the magnetic field produced by a wireless power transmission apparatus to a wireless power receiving apparatus includes a plurality of relay coils for obtaining and relaying the magnetic field. But at least one relay coil among the relay coils has a larger impedance value than that of the remaining relay coils.
