Title (EN) WIRELESS POWER TRANSFER SYSTEM
(FR) SYSTÈME DE TRANSFERT DE PUISSANCE SANS FIL
Abstract:
(EN) Disclosed herein is a rectifier circuit for receiving an AC signal from a receiver coil in an inductive power transfer system. The circuit is configured to operate at an operating frequency. The circuit comprises a Class-E rectifier; an AC signal supplier configured to supply an AC signal to the rectifier circuit; and a resonant network having an inductor and a capacitor. The resonant network has a resonant frequency, and the ratio of the resonant frequency to the operating frequency is within the range of 1.75 to 3.
(FR) L'invention concerne un circuit redresseur destiné à recevoir un signal CA provenant d'une bobine réceptrice dans un système de transfert de puissance inductive. Le circuit est configuré pour fonctionner à une fréquence de fonctionnement. Le circuit comprend un redresseur de classe E ; un fournisseur de signal CA configuré pour fournir un signal CA au circuit redresseur ; et un circuit résonnant ayant une bobine d'induction et un condensateur. Le circuit résonnant a une fréquence de résonance, et le rapport de la fréquence de résonance à la fréquence de fonctionnement est dans la plage de 1,75 à 3.
