Title (EN) RESONANCE DETECTION AND CONTROL WITHIN A WIRELESS POWER SYSTEM
(FR) DÉTECTION ET COMMANDE DE RÉSONANCE DANS SYSTÈME D'ALIMENTATION SANS FIL
Abstract: front page image
(EN)Exemplary embodiments are directed to resonant frequency tuning. A device may include a coil (L1) for transmitting wireless power. The device may further include an element to selectively modify a resonant frequency of the transmitter according to at least one of inserting the element (cp) into the transmit coil and inductively coupling the element (L5) to the transmit coil.
(FR)Selon des modes de réalisation donnés à titre d'exemple, l'invention porte sur la syntonisation d'une fréquence de résonance. Un dispositif peut comprendre une bobine (L1) pour transmettre de l'énergie sans fil. Le dispositif peut comprendre en outre un élément pour modifier de manière sélective une fréquence de résonance de l'émetteur conformément à l'insertion de l'élément (cp) dans la bobine d'émission et/ou au couplage par induction de l'élément (L5) à la bobine d'émission.
