  • Electronic device for receiving power wirelessly and method for operating same
    Patent number: 11637454
    Abstract: An electronic device according to various embodiments of the present invention comprises: a receiving circuit for outputting an AC power received wirelessly; and a rectifier circuit for rectifying the AC power being output from the power receiving circuit. The rectifier circuit comprises a forward rectifier circuit and a reverse rectifier circuit. A first terminal of the forward rectifier circuit is connected to the receiving circuit and the reverse rectifier circuit, a second terminal of the forward rectifier circuit is connected to an output terminal, and the forward rectifier circuit comprises first transistors for rectifying the AC power during a first period.

  • Electronic device for wirelessly receiving power and method for operating the same
    Patent number: 11101695
    Abstract: An electronic device is provided. The electronic device includes a receiving circuit configured to wirelessly receive power and output AC power, a rectifying circuit configured to rectify the AC power from the receiving circuit, wherein the rectifying circuit may include a first P-MOSFET configured to transfer a positive amplitude of power to an output terminal of the rectifying circuit while the AC power has the positive amplitude and to prevent transferring a negative amplitude of power to the output terminal of the rectifying circuit while the AC power has the negative amplitude, and a forward loss compensating circuit connected with the first P-MOSFET configured to reduce a threshold voltage of the first P-MOSFET while the AC power has the positive amplitude.
