SYSTÈMES DE TRANSFERT D'ÉNERGIE PAR RÉSONANCE À OPTIMISATION DU RENDEMENT BASÉE SUR L'IMPÉDANCE DU RÉCEPTEUR
Abstract:
(EN)
The present disclosure provides systems and methods for controlling wireless power transfer systems. A wireless power transfer system includes a transmitter driven by a power source and a transmit controller, wherein the transmitter is configured to control delivery of wireless power, and a receiver inductively coupled to the transmitter, the receiver configured to receive the wireless power from the transmitter and deliver the received wireless power to a load. The receiver includes receiver electronics configured to determine a Thevenin equivalent impedance of the wireless power transfer system, determine a Thevenin equivalent source voltage of the wireless power transfer system, and control, based on the determined Thevenin equivalent impedance and the determined Thevenin equivalent source voltage, an ideal source voltage of the receiver to vary the amount of the wireless power transferred from the transmitter to the receiver.
(FR)
La présente invention concerne des systèmes et des procédés de commande de systèmes de transfert d'énergie sans fil. Un système de transfert d'énergie sans fil comprend un émetteur attaqué par une source d'alimentation et un dispositif de commande d'émission, l'émetteur étant configuré pour commander la distribution d'énergie sans fil, et un récepteur couplé par induction à l'émetteur, le récepteur étant configuré pour recevoir l'énergie sans fil provenant de l'émetteur et délivrer l'énergie sans fil reçue à une charge. Le récepteur comprend des circuits électroniques de récepteur configurés pour déterminer une impédance équivalente de Thévenin du système de transfert d'énergie sans fil, déterminer une tension de source équivalente de Thévenin du système de transfert d'énergie sans fil, et commander, sur la base de l'impédance équivalente de Thévenin déterminée et de la tension de source équivalente de Thévenin déterminée, une tension de source idéale du récepteur pour faire varier la quantité d'énergie sans fil transférée de l'émetteur au récepteur.
