Title:
SYSTEM AND METHOD FOR SPACE-ADAPTIVE WIRELESS POWER TRANSMISSION USING EVANESCENT WAVE RESONANCE
Document Type and Number:
WIPO Patent Application WO/2011/055905
Kind Code:
A2
Abstract:
According to one aspect of the present invention, a magnetic resonance wireless power transmission method comprises the following steps: enabling a source coil to transmit electrical energy to a power-transmitting resonant coil via electromagnetic induction; enabling the power-transmitting resonant coil to transmit electrical energy to a power-receiving resonant coil which has a resonant frequency identical to that of the power-transmitting resonant coil in accordance with a magnetic resonant coupling; enabling the power-receiving resonant coil to transmit electrical energy to a device coil of electronic equipment via electromagnetic induction, wherein the power-transmitting resonant coil and the power-receiving resonant coil are arranged vertically to each other or inclined at a predetermined angle.
