Title (EN) WIRELESS POWER RECEIVER AND METHOD FOR CONTROLLING THE WIRELESS POWER RECEIVER
(FR) RÉCEPTEUR DE PUISSANCE SANS FIL ET PROCÉDÉ DE COMMANDE DU RÉCEPTEUR DE PUISSANCE SANS FIL
Abstract:
(EN) A wireless power receiver and a method for controlling the wireless power receiver are provided. The wireless power receiver includes a resonant circuit configured to receiving electromagnetic waves from a wireless power transmitter and output alternate current (AC) power, a rectifier configured to rectify the AC power received from the resonant circuit into direct current (DC) power, a DC/DC converter configured to convert the rectified DC power received from the rectifier and output the converted DC power, a battery, a charger configured to charge the battery with the converted DC power, and a controller configured to, upon detection of an event indicating a change in impedance at an output end of the DC/DC converter, control the impedance at the output end of the DC/DC converter to be kept constant by adjusting voltage at the output end of the DC/DC converter.
(FR) Récepteur de puissance sans fil et un procédé de commande du récepteur de puissance sans fil. Le récepteur de puissance sans fil comprend un circuit résonant conçu pour recevoir des ondes électromagnétiques provenant d'un émetteur de puissance sans fil et sortir une puissance à courant alternatif (CA), un redresseur conçu pour redresser la puissance CA reçu en provenance du circuit résonant en puissance de courant continu (CC), un convertisseur CC-CC conçu pour convertir la puissance CC redressée reçue en provenance du redresseur et sortir la puissance CC convertie, une batterie, un chargeur conçu pour charger la batterie avec la puissance CC convertie, et un dispositif de commande conçu pour, lors de la détection d'un événement indiquant un changement d'impédance au niveau d'une extrémité de sortie du convertisseur CC-CC, commander l'impédance au niveau de l'extrémité de sortie du convertisseur CC-CC pour la maintenir constante grâce à l'ajustement de la tension au niveau de l'extrémité de sortie du convertisseur CC-CC
