Description

technical field [0001] The invention relates to the technical field of wireless power transmission. Background technique [0002] As a new type of power transmission, magnetic coupling resonant wireless power transfer has higher transmission efficiency and is easier to implement. Therefore, Wireless Power Transfer is widely used in electric vehicle charging, medical equipment, water The field of lower equipment power supply has received extensive attention. [0003] Wireless charging technology has now studied a rotating transmitting coil wireless power transfer system that can realize wireless power transfer in all spaces. However, in the prior art, the transmission efficiency of the charging equipment is low when charging an object with a magnetic shielding material in the device shell but not a fully enclosed structure, resulting in a large amount of energy waste, and in the process of charging multiple objects and multiple coils, Due to the phenomenon of mutual magneti...
