无线充电耦合器的高耦合系数可以提高传输效率。为了获得较高的耦合系数，推导了双D（DD）耦合器的等效磁路和耦合系数表达式，为磁芯的优化设计提供了指导。设计并优化了一种新型的DD线圈铁芯结构，并通过三维有限元仿真和实验验证了其性能。最后，描述了一个通用的过程，以设计和优化不同的无线充电耦合器的核心结构。
The high coupling coefficient of a wireless charging coupler can improve the transmission efficiency. To obtain a higher coupling coefficient of double D (DD) coupler, the equivalent magnetic circuit and the expression of coupling coefficient are derived, giving some guidance for magnetic core optimization. A new core structure is designed and optimized for DD coils, and its performance is verified by 3-D finite element method simulation and experiments. Finally, a universal process is described to design and optimize core structures for different wireless charging couplers.
