OMNI-DIRECTIONAL RESONATOR FOR WIRELESS POWER TRANSMISSION ON X-Y PLANE USING CRISSCROSS STRUCTURE, WIRELESS POWER TRANSFER DEVICE AND WIRELESS POWER TRANSFER SYSTEM INCLUDING SAME

摘要

A resonator for wireless power transmission includes: a pillar-shaped resonator; and a resonance coil which is connected to a power source, penetrates a lower part, a side, and an upper part of the resonator, penetrates the side of the resonator at least four times so as to be parallel to the center line of the pillar-shaped resonator, and has a cross-shaped structure which does not intersect when viewed from the upper part of the resonator and the lower part of the resonator. Accordingly, the present invention can constantly maintain output in a two-dimensional direction, thereby increasing the transmission efficiency of wireless power power transmission and the degree of freedom of a receiver.;COPYRIGHT KIPO 2017
