Description

Apparatus for receiving a wireless magnetic resonance signal, Electronic device, and wireless charging system The technical concept of the present invention relates to magnetic resonance wireless charging technology, and more specifically, to a wireless signal receiver that varies to couple a standard frequency signal for wireless charging that is continuously transmitted according to the permission of a management server, an electronic device utilizing the same, and a wireless charging system. Wireless charging methods include contact-based magnetic induction, and non-contact methods such as magnetic resonance and electromagnetic waves. Contact-based magnetic induction has already been commercialized and standardized. However, while magnetic induction offers relatively high wireless signal transmission efficiency, it has limitations in transmission distance, as the range is only a few millimeters to a few centimeters. Meanwhile, in the case of the electromagnetic wave method of non-contact wireless charging, the transmission distance is up to tens of km, but the transmission efficiency is only 10% to 50%, so it has limitations in transmission efficiency and also poses a risk to the human body. Accordingly, non-contact wireless charging associations and organizations are preparing for standardization, and recently, various research and development are underway for the commercialization of the magnetic resonance method, which secures a transmission distance in the range of several meters and has a higher transmission efficiency than the electromagnetic wave method. In the future, electronic devices equipped with battery modules requiring charging (e.g., smartphones) will enter the market equipped with wireless signal receivers that couple standard frequency signals for contactless wireless charging. Consequently, the wireless signal receiver mounted on the device will match the standard frequency signal for wireless charging generated by the wireless signal transmitter, facilitating charging. However, unlike networks such as Wi-Fi, contactless wireless charging technology cannot be controlled by passwords. This is because electricity is generated and charging begins immediately when the wireless charging frequency signals are coupled. Therefore, early transmitter installers require technology capable of controlling the standard frequency coupling operation of wireless signal receivers to ensure the success of the contactless wireless charging business.
