Title
(EN) WIRELESS POWER TRANSCEIVER AND DISPLAY APPARATUS WITH THE SAME
(FR) ÉMETTEUR-RÉCEPTEUR DE PUISSANCE SANS FIL ET APPAREIL D'AFFICHAGE DOTÉ DE CELUI-CI
Abstract
(EN)
Provided is a wireless power transceiver including a magnetic body formed in a rod shape with a groove in a middle portion thereof, a solenoid coil wound around the middle portion of the magnetic body in which the groove is formed, and a dual coil disposed substantially perpendicular to the solenoid coil and wound around portions of both sides of the groove of the magnetic body, the dual coil being wound in directions opposite to each other.
(FR)
L'invention concerne un émetteur-récepteur de puissance sans fil comprenant un corps magnétique formé en forme de tige avec une rainure dans une partie centrale de celui-ci, une bobine de solénoïde enroulée autour de la partie centrale du corps magnétique dans laquelle la rainure est formée, et une bobine double disposée sensiblement perpendiculairement à la bobine de solénoïde et enroulée autour de parties des deux côtés de la rainure du corps magnétique, la double bobine étant enroulée dans des directions opposées les unes aux autres.
