Samsung patents wireless charging that adjusts voltage for better efficiency

Samsung has been granted a patent for a method that helps electronic devices transmit wireless power more efficiently. The system monitors the frequency used to send power and automatically adjusts the internal voltage when the frequency drops into specific lower or higher ranges. This adjustment aims to optimize the charging circuit's performance during the transmission process.

Why it mattersThis is a technical improvement to how wireless charging hardware manages power, potentially making the process more stable or efficient for users.

In the filing’s own words

According to various embodiments, an electronic device comprises: a power supply unit comprising a power supply; an antenna module including at least one antenna; a magnetic field control circuit electrically connected to the antenna module; a charging circuit electrically connected to the power supply unit and the magnetic field control circuit; and at least one processor electrically connected to the magnetic field control circuit and the charging circuit, wherein the at least one processor may be configured to: identify an operating frequency through the magnetic field control circuit during the transmission of wireless power outside of the electronic device through the antenna module using power supplied from the power supply unit, identify whether the confirmed operating frequency is included in at least one operating voltage change frequency section within the designated operating frequency range, and change the operating voltage of the charging circuit based on the operating frequency being included in the at least one operating voltage change frequency section.

What exactly they claim (claim 1)

1. An electronic device comprising: a power supply unit comprising a power supply; an antenna module comprising at least one antenna; a magnetic field controller circuit electrically connected to the antenna module; a charging circuit electrically connected to the power supply unit and the magnetic field controller circuit; memory storing instructions; and at least one processor, wherein the instructions, when executed by the at least one processor, cause the electronic device to: identify an operating frequency through the magnetic field controller circuit during wireless power transmission to outside of the electronic device through the antenna module using power supplied from the power supply unit, based on the identified operating frequency being included between a lowest frequency and a first operating threshold frequency or between a second operating threshold frequency higher than the first operating threshold frequency and a highest frequency within a specified operating frequency range, change an operating voltage of the charging circuit from a first operating voltage to a second operating voltage different from the first operating voltage; based on the identified operating frequency being included between the first operating threshold frequency and the second operating threshold frequency within the specified operating frequency range, maintain the operating voltage of the charging circuit as the first operating voltage.
