Title
(EN) SHAPED COIL FOR WIRELESS POWER TRANSMISSION SYSTEM COUPLING
(FR) BOBINE FAÇONNÉE POUR COUPLAGE DE SYSTÈME DE TRANSMISSION D'ÉNERGIE SANS FIL
Abstract
(EN) A wireless power transfer system includes an antenna base having a charger surface configured substantially as a concave spherical section and a first antenna comprising a spiral wire coil conforming to the charger surface of the antenna base. A target item includes an interface surface configured as a convex spherical section substantially matching the concave spherical section of the charger base. A second antenna is located within the target item and adjacent to the interface surface such that when the target item is placed in the antenna base with the interface surface mated to the charger surface, the first and second antennas are within inductive coupling range for wireless power transfer between the antennas.
(FR) La présente invention concerne un système de transfert d'énergie sans fil qui comprend une base d'antenne ayant une surface de chargeur conçue sensiblement sous la forme d'une section sphérique concave et une première antenne comprenant une bobine de fil en spirale se conformant à la surface de chargeur de la base d'antenne. Un article cible comprend une surface d'interface conçue sous la forme d'une section sphérique convexe correspondant sensiblement à la section sphérique concave de la base de chargeur. Une seconde antenne est située à l'intérieur de l'élément cible et adjacente à la surface d'interface de telle sorte que, lorsque l'élément cible est placé dans la base d'antenne, la surface d'interface accouplée à la surface de chargeur, les première et seconde antennes se trouvent dans une plage de couplage inductif pour un transfert de puissance sans fil entre les antennes.
