  • Wireless power transfer system
    Patent number: 11404911
    Abstract: 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.
