Abstract

La présente invention a trait à un procédé d'adaptation d'inductances pour une charge sans fil et à des dispositifs associés. Le procédé d'adaptation d'inductances dans un émetteur de puissance sans fil, destiné à une transmission sans fil de puissance, peut comprendre, selon un mode de réalisation de la présente invention, les étapes consistant à : détecter un objet disposé dans une région de charge; lorsque l'objet est détecté, mesurer une valeur de facteur de qualité; sur la base de la valeur de facteur de qualité mesurée, estimer une valeur d'inductance d'un récepteur de puissance sans fil; déterminer si un réglage d'inductance est nécessaire par comparaison d'une valeur d'inductance de l'émetteur de puissance sans fil à la valeur d'inductance du récepteur de puissance sans fil; et, selon les résultats de la détermination, régler la valeur d'inductance de l'émetteur de puissance sans fil. Ainsi, ladite invention présente l'avantage que l'efficacité de charge peut être rendue maximale par un réglage dynamique d'une valeur d'inductance propre selon une valeur d'inductance d'un autre objet.
