Analysis and Validation on Characteristic of Orientation in Wireless Power Transfer System via Coupled Magnetic Resonances
摘要
Abstract
In order to confirm whether the angle deflection will influence the power of receiver coils in wireless power transfer system, the characteristic of orientation in wireless power transfer system is analyzed by the coupling model of two spatial isolated coils and its equivalent circuit firstly, and then yielded the frequency response curve of normalized voltage in the receiver coils and necessary condition for wireless power transfer. Characteristic of orientation in the case of overcoupling, critical coupling and undercoupling was presented after the effect to coupling factor is analyzed by orientation deflection according to the relationship between the coupling coefficient of two spatial isolated coils and orientation. In the end, experiment circuit is designed and experimental results are well consistent with the theoretical analysis, which shows the correctness of the proposed method and its result. Thus provides an useful reference for the design of wireless power transfer system for mobile device and its parameters optimization.关键词
