非接触式电力传输由于其在现代技术中的许多应用而受到关注。文献中提出了近场传输的不同拓扑结构，重点是该过程的效率，特别是当此类系统用于中功率或高功率时，例如电动/混合动力汽车中蓄电池充电所需的拓扑结构。本文分析了在电源和负载之间提供磁感应传输的系统关键元件之一，即电感耦合器。为了快速识别其参数，本文采用矢量网络分析仪（VNA）自动确定传递函数。
Contactless power transmission is a major concern due to its many applications in the modern technique. Different topologies for near field transmission are presented in literature, with emphasis on the efficiency of the process, especially when such systems are used for medium or high power, like those needed for charging of storage batteries in electric/hybrid cars. This paper analyzes one of the system's key elements which provides the magnetic inductive transfer between the power supply and load, hereinafter referred to as inductive coupler. For a fast identification of its parameters, the automatic determination of the transfer function by a vector network analyzer (VNA) is used in this paper.
