Title (EN) METHOD FOR ADAPTIVE LOAD MODULATION
(FR) PROCÉDÉ DE MODULATION DE CHARGE ADAPTATIVE
Abstract:
(EN) The present invention provides for an apparatus and method to change the load of the load modulation along with the changes of the overall load, so that communication between an energy transmitter (Tx) and an energy receiver (Rx) of a wireless charging system during charging could be detected and improved. The inventive apparatus and method make use of variable resistance and controllers to assist with modulating load resistance to modulate load current for wireless energy receiver under charge. The inventive method and apparatus assist with improved communication in wireless charging systems.
(FR) La présente invention concerne un appareil et un procédé pour modifier la charge de la modulation de charge au même titre que les modifications de la charge globale, de telle sorte qu'une communication entre un émetteur d'énergie (Tx) et un récepteur d'énergie (Rx) d'un système de charge sans fil pendant la charge puisse être détectée et améliorée. L'appareil et le procédé de l'invention utilisent une résistance variable et des dispositifs de commande pour aider à moduler la résistance de charge afin de moduler le courant de charge pour un récepteur d'énergie sans fil en charge. Le procédé et l'appareil de l'invention permettent d'améliorer une communication dans des systèmes de charge sans fil.
