Abstract
(EN)
This disclosure provides systems, methods and apparatus for wirelessly transferring power using parasitic resonators. In one aspect a wireless power receiver apparatus for powering or charging an electric vehicle (2412) is provided. The wireless power receiver apparatus includes a receive circuit including a first coil (2416). The receive circuit is configured to wirelessly receive power so as to power or charge or power the electric vehicle. The wireless power receiver apparatus further includes a passive circuit including a second coil (2403). The passive circuit is configured to wirelessly receive power from a transmit circuit including a third coil (2404). The passive circuit is further configured to wirelessly retransmit power received from the transmit circuit to the receive circuit. The wireless power receiver apparatus further includes a controller (2444, 2454) configured to displace the second coil (2403) from the first coil (2416) is provided.

La présente invention porte sur des systèmes, des procédés et un appareil de transfert sans fil d'énergie à l'aide de résonateurs parasites. Selon un aspect, un appareil récepteur d'énergie sans fil servant à alimenter ou à charger un véhicule électrique (2412) est prévu. L'appareil récepteur d'énergie sans fil comprend un circuit de réception comprenant une première bobine (2416). Le circuit de réception est configuré pour recevoir sans fil de l'énergie de façon à alimenter ou à charger le véhicule électrique. L'appareil récepteur d'énergie sans fil comprend en outre un circuit passif comprenant une deuxième bobine (2403). Le circuit passif est configuré pour recevoir sans fil de l'énergie provenant d'un circuit d'émission comprenant une troisième bobine (2404). Le circuit passif est en outre configuré pour retransmettre sans fil l'énergie reçue du circuit d'émission au circuit de réception. L'appareil récepteur d'énergie sans fil comprend en outre un dispositif de commande (2444, 2454) configuré pour déplacer la deuxième bobine (2403) par rapport à la première bobine (2416).
