Title (EN) A WIRELESS CHARGING DEVICE, A RECEIVER DEVICE, AND AN ASSOCIATED METHOD THEREOF
(FR) DISPOSITIF DE CHARGE SANS FIL, DISPOSITIF RÉCEPTEUR ET PROCÉDÉ ASSOCIÉ S'Y RAPPORTANT
Abstract:
(EN) A wireless charging device (102) is disclosed. The wireless charging device (102) includes a transmitter detection coil (130) configured to receive a first alternating current (AC) voltage signal having a characteristic associated with a receiver device (104). Also, the wireless charging device (102) includes a control unit (112) coupled to the transmitter detection coil (130) and configured to detect the receiver device (104) based on the characteristic of the first AC voltage signal. Further, the wireless charging device (102) includes a driver unit (108) coupled to the control unit (112) and configured to convert a direct current (DC) voltage signal of an input power to a second AC voltage signal if the receiver device (104) is detected. In addition, the wireless charging device (102) includes a power transmission coil (116) configured to wirelessly transmit the second AC voltage signal to the receiver device (104).
(FR) La présente invention concerne un appareil de charge sans fil (102). Le dispositif de charge sans fil (102) comprend une bobine de détection d'émetteur (130) configurée de sorte à recevoir un premier signal de tension alternative (CA) ayant une caractéristique associée à un dispositif récepteur (104). En outre, le dispositif de charge sans fil (102) comprend une unité de commande (112) couplée à la bobine de détection d'émetteur (130) et configurée de sorte à détecter le dispositif récepteur (104) sur la base de la caractéristique du premier signal de tension alternative. En outre, le dispositif de charge sans fil (102) comprend une unité d'attaque (108) couplée à l'unité de commande (112) et configurée de sorte à convertir un signal de tension continue (CC) d'une puissance d'entrée en un second signal de tension alternative si le dispositif récepteur (104) est détecté. De plus, le dispositif de charge sans fil (102) comprend une bobine de transmission de puissance (116) configurée de sorte à transmettre sans fil le second signal de tension alternative au dispositif récepteur (104).
