Description

technical field [0001] This product relates to a wireless power transmission system, in particular to a wireless power transmission system with a safe load identification function and an implementation method thereof. Background technique [0002] The wireless power transmission technology usually uses the principle of electromagnetic induction to work, and the normal power supply can only be performed when the electrical load of the receiving end needs to be close to the area of ​​the transmitting end. For the convenience of users, the system usually has the function of automatic load recognition, that is, the transmitter can sense whether a load enters or removes the working area, thereby turning on or off the wireless power supply system. This load identification method is usually carried out by monitoring the amplitude change of the resonant current on the transmitter coil. However, when objects with metal materials (such as metal keys, knives, etc.) are also placed in ...
