Title (EN) INDUCTIVE POWER TRANSMITTER
(FR) ÉMETTEUR DE PUISSANCE INDUCTIVE
Abstract:
(EN) An inductive power transmitter comprising an LCL circuit which includes a transmitter coil; and a power inverter including a plurality of control devices configured to drive the LCL circuit; wherein the frequency of a plurality of drive signals for the respective control devices is determined based on a desired power factor for the LCL circuit.
(FR) Émetteur de puissance inductive comprenant un circuit LCL qui comprend une bobine émettrice; et un inverseur de puissance comprenant une pluralité de dispositifs de commande conçus pour entraîner le circuit LCL; la fréquence d'une pluralité de signaux de commande pour les dispositifs de commande respectifs étant déterminée sur la base d'un facteur de puissance souhaité pour le circuit LCL.
