Abstract
Description
technical field
[0001] The invention relates to electromagnetic coupling technology, in particular to a magnetic core structure used in a wireless energy transmission system and an electromagnetic coupling device based on the magnetic core structure. Background technique
[0002] Wireless power transfer technology (Inductive Power Transfer), referred to as IPT technology, is a new technology that transfers energy to loads in a non-contact manner through electromagnetic coupling. The electromagnetic coupling mechanism is a key module to realize the wireless transmission of electric energy, and its design is related to various indicators such as the transmission distance, transmission range and transmission efficiency of the IPT system. The electromagnetic coupling mechanism is composed of an energy emitting mechanism and an energy picking mechanism. For mobile devices, their wireless power transmission methods are generally divided into two types: fixed-point transmission an...
