Abstract
L’invention propose un procédé de détection d’un objet métallique étranger, par un dispositif de charge (D’), comprenant un microcontrôleur (10’) et un circuit émetteur (E) comprenant au moins une antenne émettrice (B1), adaptés pour charger à une fréquence de fonctionnement (FRF) un équipement portable d’utilisateur (P) posé sur une surface de charge (S), le procédé étant caractérisé en ce qu’il comprend les étapes suivantes : a) Emission d’un nombre prédéterminé (N) d’impulsions de tensions (P1) aux bornes de l’antenne émettrice (B1), à une fréquence de résonance parasite (FRP), ladite fréquence de résonance parasite étant différente et distincte de la fréquence de fonctionnement, b) Détermination d’une fréquence d’oscillation du circuit émetteur (FE), c) Si la fréquence d’oscillation (FE) est supérieure à la fréquence de résonance parasite (FRP), alors un objet métallique étranger est détecté sur la surface de charge (S).
