Title (EN) WIRELESS CHARGING COIL PLACEMENT FOR REDUCED FIELD EXPOSURE
(FR) PLACEMENT DE BOBINE DE CHARGE SANS FIL POUR EXPOSITION RÉDUITE AU CHAMP
Abstract:
(EN) An apparatus is described herein. The apparatus includes a power transmit unit coil and an active shielding coil. The power transmit unit coil includes a set of main windings, positioned at a first location on a structure, to carry a first current in a first direction, wherein the first current is to cause an electromagnetic field to emanate from the power transmit unit coil. The active shielding coil is positioned at a second location on the structure and is to carry a second current in a direction substantially opposite the first direction wherein the second current is to cause a reduction of the size of the electromagnetic field.
(FR) L'invention concerne un appareil. L'appareil comprend une bobine d'unité d'envoi d'énergie et une bobine de blindage active. La bobine d'unité d'envoi d'énergie comprend un ensemble d'enroulements principaux, positionnés à un premier emplacement sur une structure, pour transporter un premier courant dans une première direction, le premier courant servant à faire émaner un champ électromagnétique de la bobine d'unité d'envoi d'énergie. La bobine de blindage active est positionnée à un second emplacement sur la structure et est destinée à transporter un second courant dans une direction sensiblement opposée à la première direction, le second courant servant à provoquer une réduction de l'amplitude du champ électromagnétique.
