Title (EN) WIRELESS CHARGING METHOD, AND APPARATUS AND SYSTEM THEREFOR
(FR) PROCÉDÉ DE CHARGEMENT SANS FIL, ET APPAREIL ET SYSTÈME ASSOCIÉS
(KO) 무선 충전 방법 및 그를 위한 장치 및 시스템
Abstract:
(EN) The present invention relates to a wireless charging method, and an apparatus and a system therefor. A wireless charging method in a wireless power transmitter, according to an embodiment of the present invention, may comprise the steps of: controlling transmission power on the basis of a feedback signal periodically received from a wireless power receiver during power transmission; determining whether or not the wireless power receiver is present in a charging area during the power transmission; and maintaining the intensity of the transmission power constant if the result of the determination shows that the wireless power receiver is not present in the charging area. Therefore, the present invention is advantageous in that it is possible to prevent, in advance, the power transmission from being unnecessarily interrupted against a user's intention.
(FR) La présente invention concerne un procédé de chargement sans fil, et un dispositif et un système associés. Un procédé de chargement sans fil dans un émetteur de puissance sans fil, selon un mode de réalisation de la présente invention, peut comprendre les étapes consistant à : contrôler la puissance de transmission d'après un signal de rétroaction reçu périodiquement d'un récepteur de puissance sans fil durant la transmission de puissance; déterminer si le récepteur de puissance sans fil est présent ou non dans une zone de chargement durant la transmission de puissance; et maintenir l'intensité de la puissance de transmission de sorte qu'elle soit constante si le résultat de la détermination indique que le récepteur de puissance sans fil n'est pas présent dans la zone de chargement. La présente invention est avantageuse en ce qu'elle permet d'empêcher, à l'avance, toute interruption accidentelle de la transmission de puissance.
(KO) 본 발명은 무선 충전 방법 및 그를 위한 장치 및 시스템에 관한 것으로서, 본 발명의 일 실시예에 따른 무선 전력 송신기에서의 무선 충전 방법은 전력 전송 중 무선 전력 수신기로부터 주기적으로 수신되는 피드백 신호에 기반하여 송출 전력을 제어하는 단계와 상기 전력 전송 중 상기 무선 전력 수신기가 충전 영역에 존재하는지 여부를 판단하는 단계와 상기 판단 결과, 상기 무선 전력 수신기가 상기 충전 영역에 존재하지 않는 경우, 상기 송출 전력의 세기를 일정하게 유지시키는 단계를 포함할 수 있다. 따라서, 본 발명은 사용자의 의도에 반하여 불필요하게 전력 전송이 중단되는 현상을 미연에 방지할 수 있는 장점이 있다.
