Electronic device and wireless power supply system and method thereof

Abstract

An electronic device (100), a wireless power supplying system (10) thereof and a wireless power supplying method thereof. The electronic device (100) includes an internal function circuit (30) and the wireless power supplying system (10). The wireless power supply system (10) includes a wireless electric power emission terminal (11), a wireless electric power receiving terminal (12) and a power supply detection unit (13). The wireless electric power emission terminal (11) includes a transmission terminal control module (111) and an emission terminal power supplying module (112) which are electrically coupled with each other. The wireless electric power receiving terminal (12) wirelessly receives the electric power from the emission terminal power supplying module (112). The power supply detection unit (13) includes an electric power detection module (131), a processor (132) and a warning module (133), which are electrically coupled in turn. The electric power detection module (131) detects an operating voltage received from the wireless electric power receiving terminal (12); and the processor (132) compares the operating voltage with a built-in preset operating voltage range. When the operating voltage is within the preset operating voltage range, the operating voltage is outputted to the internal function circuit (30), and when the operating voltage is beyond the preset range, the processor (132) generates a warning signal and sends the signal to a warning module (133).

Description

technical field [0001] The present invention relates to wireless power supply technology, and in particular to an electronic device adopting wireless power supply, a wireless power supply system and a wireless power supply method used in the electronic device. Background technique [0002] Household electronic devices such as televisions draw power from a power source, usually through direct contact between conductors. Therefore, when an electronic device uses a power source, such as an AC power source, a power cord needs to be connected to the power source. However, due to the limitation of the power cord, the placement of household electronic devices such as televisions is limited, which brings great inconvenience to users. the inconvenience. [0003] At present, a wireless power supply technology that uses magnetic coupling resonance for power transmission has been proposed. It uses non-radiative magnetic coupling, that is, two resonant objects of the same frequency prod...
