感应电能传输线圈利兹线屏蔽层的电路模型与快速优化

The metal shields with plates or rings are usually added to the inductive-power-transfer coils to attenuate the stray magnetic field. However, the coil-to-coil efficiency is reduced owning to the extra losses on the shields. This paper introduces the litz shield which attenuates the field with smaller shielding loss thanks to the uniform distribution of the shield current. Two types of litz shield...
