Abstract

Strong coupled magnetic resonance Wireless Power Transfer (WPT) proposed by
researchers at Qi IEEE conf. in 2007 attracted the world’s attention by virtue of its
mid-range, non- radioactive, and high-efficiency power transfer. In this article,
current developments and research progress in the technology of WPT are
presented. Advantage of WPT are analysed by comparing it with other WPT
technologies and different analytic principles of WPT are elaborated in depth and
further compared. The important research areas, including system architectural
analysis, frequency splitting phenomena, impedance matching, and optimization
designs are classified and elaborated. Finally, current research directions and
development trends of WPT are discussed and the simulation results are presented
as convincing evidences that the proposed model meets the design specifications
and it is capable of providing efficient wireless power transfer to portable charging
devices.
