Title (EN) A WIRELESS CHARGING DEVICE, A RECEIVER DEVICE, AND A METHOD OF OPERATING THE SAME
(FR) DISPOSITIF DE CHARGE SANS FIL, DISPOSITIF RÉCEPTEUR ET SON PROCÉDÉ DE FONCTIONNEMENT
Abstract:
(EN) A wireless charging device (102) includes a driver unit (110) configured to generate one of a first AC voltage signal having a first frequency and a second AC voltage signal having a second frequency. Also, the wireless charging device (102) includes a transmitting unit (114) having a first coil (130) and a first capacitor (132) and configured to transmit the first AC voltage signal. Further, the transmitting unit (114) includes a second coil (134) and a second capacitor (136) and configured to transmit the second AC voltage signal. Additionally, the wireless charging device (102) includes a control unit (112) configured to detect a first receiver device (104) operating at the first frequency based on a change in a first voltage in the transmitting unit (114), and detect a second receiver device (106) operating at the second frequency based on a change in a second voltage in the transmitting unit (114).
(FR) Un dispositif de charge sans fil (102) comprend une unité d'entraînement (110) configurée de façon à générer un premier signal de tension alternative présentant une première fréquence ou un second signal de tension alternative présentant une seconde fréquence. De plus, le dispositif de charge sans fil (102) comprend une unité de transmission (114) ayant une première bobine (130) et un premier condensateur (132) et configurée pour transmettre le premier signal de tension alternative. En outre, l'unité de transmission (114) comprend une seconde bobine (134) et un second condensateur (136) et est configurée pour transmettre le second signal de tension alternative. De plus, le dispositif de charge sans fil (102) comprend une unité de commande (112) configurée pour détecter un premier dispositif récepteur (104) fonctionnant à la première fréquence sur la base d'un changement d'une première tension dans l'unité de transmission (114), et pour détecter un second dispositif récepteur (106) fonctionnant à la seconde fréquence sur la base d'un changement d'une seconde tension dans l'unité de transmission (114).
