  • ACTIVE RECTIFIER HAVING MAXIMUM POWER TRANSFER AND MAXIMUM EFFICIENCY OVER DISTANCE
    Publication number: 20190181682
    Abstract: Provided is a wireless power reception device including: a gate driver for generating a gate signal for switching between a turn-on voltage and a turn-off voltage; a rectifier connected to both ends of an inductor and including FETs whose on/off states are controlled by the gate signal; a rectifier output detection unit for sensing an output value of the rectifier; and an impedance control unit for controlling an impedance of the rectifier by controlling at least one of a duty ratio of the gate signal and a turn-on voltage for turning on the FET based on the output value.
