Abstract:
A magnetic resonance wireless power transfer method according to an aspect of the present invention includes transmitting power from a source coil to the Tx resonant coil using a magnetic induction method, transmitting the power from the Tx resonant coil to an Rx resonant coil, having a resonant frequency identical with that of the Tx resonant coil, via magnetically-coupled resonance, and transmitting the power from the Rx resonant coil to the device coil of an electronic device using the magnetic induction method. The Tx resonant coil and the Rx resonant coil are arranged at a right angle or a specific angle of inclination relative to each other.
