Title
(EN) ADAPTIVE WIRELESS POWER TRANSMITTER
(FR) ÉMETTEUR DE PUISSANCE SANS FIL ADAPTATIF
Abstract
(EN)
A method for wirelessly charging, by a transmitter, at least one receiver placed above at least one coil having at least one section, the method comprising: determining a plurality of charging locations that form a charging area above the at least one coil; determining a matrix of magnetic field contributions of each section in the at least one coil to each charging location of the plurality of charging locations; determining a magnetic field pattern of the charging area; calculating a current vector that comprises a current value for the each section in the at least one coil; and driving, by the transmitter, the each section in the at least one coil with the current vector for shaping the magnetic field pattern.
(FR)
L'invention concerne un procédé de charge sans fil, par un émetteur, d'au moins un récepteur placé au-dessus d'au moins une bobine ayant au moins une section, le procédé consistant à : déterminer une pluralité d'emplacements de charge qui forment une zone de charge au-dessus de la ou des bobines; déterminer une matrice de contributions de champ magnétique de chaque section dans la ou les bobines vers chaque emplacement de charge de la pluralité d'emplacements de charge; déterminer un motif de champ magnétique de la zone de charge; calculer un vecteur de courant qui comprend une valeur de courant pour chaque section dans la ou les bobines; et commander, par l'émetteur, chaque section dans la ou les bobines avec le vecteur de courant pour mettre en forme le motif de champ magnétique.
