==ELECTRONIC DEVICE FOR CONTROLLING PHASE DIFFERENCE OF POWER PROVIDED  TO RECTIFIER, AND METHOD FOR CONTROLLING SAME - A simplified explanation of the abstract==


*This abstract for appeared for patent application  number 18335015 Titled 'ELECTRONIC DEVICE FOR CONTROLLING PHASE DIFFERENCE OF POWER PROVIDED  TO RECTIFIER, AND METHOD FOR CONTROLLING SAME'

==Simplified Explanation==

The abstract describes an electronic device that can receive power wirelessly. It includes a resonance circuit with a battery, coil, and capacitor, which receives alternating current power. This power is then rectified into direct current power by a rectifying circuit with multiple transistors. The device also has a control circuit that identifies the phase difference between the voltage and current of the received power and adjusts the bias voltage of the transistors to ensure impedance matching. This helps optimize the power transfer between the device and the external electronic device providing the power.


==Original Abstract Submitted==

An electronic device may include: a resonance circuit including a battery, a coil, and a capacitor, and configured to receive power wirelessly; a rectifying circuit including multiple transistors, and configured to rectify alternating current power provided from the resonance circuit into direct current power; and a control circuit, wherein the control circuit is configured to: identify a difference between the phase of voltage and the phase of current of the alternating current power provided from the resonance circuit during wireless reception of power from an external electronic device; and perform impedance matching by controlling the bias voltage of at least one of the multiple transistors on the basis that the difference between the phase of voltage and the phase of current satisfies a designated condition.
