(FR) TECHNIQUES DE TRANSFERT D'ÉNERGIE SANS FIL
Abstract
(EN) The present disclosure relates to a wireless power transmitter device (101), the wireless power transmitter device comprising: at least one transmitter coil (102) acting as inductive element of at least one inductive-capacitive resonator that upon excitation with a time-varying voltage produces a time varying electromagnetic field (107) causing a circulating electric field through at least one receiver coil of a wireless power receiver device (108) for charging the wireless power receiver device (108), wherein the at least one transmitter coil (102, 300) is composed of at least two spirals (301, 303) electrically connected (302, 304) to each other, wherein the at least two spirals (301, 303) are oriented in space to form a composed geometric figure. The disclosure further relates to a corresponding wireless power receiver device (108).
(FR) La présente invention concerne un dispositif émetteur de puissance sans fil (101), le dispositif émetteur de puissance sans fil comprenant : au moins une bobine émettrice (102) agissant en tant qu'élément inductif d'au moins un résonateur inductif-capacitif qui, lors de l'excitation avec une tension variant dans le temps, produit un champ électromagnétique variant dans le temps (107) faisant circuler un champ électrique circulant à travers au moins une bobine réceptrice d'un dispositif récepteur d'énergie sans fil (108) pour charger le dispositif récepteur d'énergie sans fil (108), ladite au moins une bobine émettrice (102, 300) est composée d'au moins deux spirales (301, 303) reliées électriquement (302, 304) l'une à l'autre, lesdites au moins deux spirales (301, 303) étant orientées dans l'espace pour former une figure géométrique composée. L'invention concerne en outre un dispositif récepteur de puissance sans fil correspondant (108).
