Abstract
The present invention provides a resonant wireless power receiver circuit, comprising: a resonant circuit for receiving a wireless power to generate a AC resonant signal which has an amplitude; a bridge rectifier circuit which includes a multi-mode switch, for rectifying the AC resonant signal to a rectifier output signal to drive a load, wherein the rectifier output signal includes a rectifier output voltage and a rectifier output current; and a feedback control circuit for generating a switch control signal according to a feedback signal related to the rectifier output signal to control the multi-mode switch to operate in a Conductive Operation at least for a partial time in a cycle period, such that the rectifier output voltage is substantially twice the amplitude, or the rectifier output voltage corresponds to an output voltage reference and/or the rectifier output voltage corresponds to an output current reference.
