用于电动车辆的无线电力传输系统需要具有高效率、大的气隙和对横向方向上的未对准的良好容限，并且需要紧凑且重量轻。一个新的3千瓦的Transformer已开发，以满足这些标准，使用一种新的H形的核心和分裂的初级电容器。基于耦合系数k，绕组的Q，和磁芯损耗的设计过程进行了描述。在200 mm的气隙内实现了90%的效率。
A wireless power transfer system for electric vehicles is required to have high efficiency, a large air gap, and good tolerance for misalignment in the lateral direction and to be compact and lightweight. A new 3 kW transformer has been developed to satisfy these criteria using a novel H-shaped core and split primary capacitors. The design procedure based on the coupling factor k, the winding's Q, and the core loss is described. An efficiency of 90% was achieved across a 200 mm air gap.
