Abstract
(EN)
Disclosed is an electronic device. A wireless power transferring device includes a first interface comprising interface circuitry, a conversion circuit, a coil, and a control circuit. The control circuit is configured to control the device to communicate with the power supply device to identify maximum supply power of the power supply device and set maximum transfer power to the maximum supply power or less based on the power supply device being connected to the first interface, to generate the transfer power based on power supplied from the power supply device using the conversion circuit, to transfer the generated transfer power to a wireless power receiving device using the coil, to determine whether the request is for power adjustment exceeding the maximum transfer power based on receiving a request for power adjustment from the wireless power receiving device, to adjust the transfer power using the conversion circuit in response to the request based on the request not being for power adjustment exceeding the maximum transfer power, and to ignore the request to adjust the transfer power based on the request for power adjustment exceeding the maximum transfer power.
(FR)
L'invention concerne un dispositif électronique. Un dispositif de transfert d'énergie sans fil comprend une première interface comprenant un ensemble circuit d'interface, un circuit de conversion, une bobine et un circuit de commande. Le circuit de commande est configuré pour commander le dispositif afin de communiquer avec un dispositif d'alimentation électrique pour identifier une puissance d'alimentation maximale du dispositif d'alimentation électrique et de définir une puissance de transfert maximale à la puissance d'alimentation maximale ou moins sur la base du fait que le dispositif d'alimentation électrique est connecté à la première interface, de générer la puissance de transfert sur la base d'une puissance fournie par le dispositif d'alimentation électrique à l'aide du circuit de conversion, de transférer la puissance de transfert générée à un dispositif de réception d'énergie sans fil à l'aide de la bobine, de déterminer si la demande est pour un réglage de puissance dépassant la puissance de transfert maximale sur la base de la réception d'une demande de réglage de puissance en provenance du dispositif de réception d'énergie sans fil, de régler la puissance de transfert à l'aide du circuit de conversion en réponse à la demande sur la base du fait que la demande n'est pas pour un réglage de puissance dépassant la puissance de transfert maximale, et d'ignorer la demande de réglage de la puissance de transfert sur la base du fait que la demande de réglage de puissance dépasse la puissance de transfert maximale.
