Summary:A wireless power transmitter according to an embodiment of the present specification comprises: a power converter comprising a primary coil magnetically coupled to a secondary coil of a wireless power receiver to transmit wireless power; and a controller for communicating with the wireless power receiver and controlling the wireless power transmission, wherein the controller receives first information relating to the secondary coil from the wireless power receiver, receives second information relating to the position information of the wireless power receiver from the wireless power receiver, and distinguishes a state in which a foreign material is present between the wireless power receiver and the wireless power transmitter, and a misalignment state of the primary coil and secondary coil, on the basis of the first information and second information. Un émetteur d'énergie sans fil selon un mode de réalisation de la présente spécification comprend : un convertisseur d'énergie comprenant une bobine primaire accouplée magnétiquement à une bobine secondaire d'un récepteur d'énergie sans fil pour transmettre de l'énergie sans fil ; et un dispositif de commande pour communiquer avec le récepteur d'énergie sans fil et commander la transmission d'énergie sans fil, le dispositif de commande recevant des premières informations relatives à la bobine secondaire provenant du récepteur d'énergie sans fil, recevant des secondes informations concernant les informations de position du récepteur d'énergie sans fil à partir du récepteur d'énergie sans fil, et distinguant un état dans lequel un matériau étranger est présent entre le récepteur d'énergie sans fil et l'émetteur d'énergie sans fil d'un état de décalage de la bobine primaire et de la bobine secondaire, sur la base des premières informations et des secondes informations. 본 명세서의 일 실시예에 따른 무선전력 전송장치는, 무선전력 수신장치의 2차 코일(secondary coil)과 자기 커플링(magnetic coupling)되어 상기 무선전력을 전송하는 1차 코일(primary coil)을 포함하는 전력 컨버터 및 상기 무선전력 수신장치와 통신하며 상기 무선전력의 전송을 제어하는 컨트롤러를 포함하며, 상기 컨트롤러는, 상기 무선전력 수신장치로부터 상기 2차 코일과 관련된 제1 정보를 수신하고, 상기 무선전력 수신장치로부터 상기 무선전력 수신장치의 위치 정보와 관련된 제2 정보를 수신하고, 상기 제1 정보와 상기 제2 정보를 기초로, 상기 무선전력 수신장치와 상기 무선전력 전송장치 사이에 이물질이 존재하는 상태와, 상기 1차 코일과 상기 2차 코일의 오정렬 상태를 구별한다.
