摘要 运行在高频电磁场环境下的无线电能传输系统受到电磁力的作用,长期作用将导致磁屏蔽结构损坏、线圈变形、绝缘破坏等问题。该文为削弱结构电磁力对无线电能传输系统耦合机构的影响,首先从频域角度分析无线电能传输系统耦合机构所受结构电磁力特性,确定结构电磁力作用特性与流经耦合线圈的电流相位之间的关系;然后提出一种基于相差调控的结构电磁力平抑方法,利用双线并行型耦合结构,通过调节串接在某发射线圈支路的可调支路电感量,实现对流经耦合线圈的电流相位的调控;最后实现耦合机构宏观受力表现的削弱,同时搭建实验平台验证平抑方法的有效性。

Abstract:The wireless power transmission system operating in the high-frequency electromagnetic field environment is subjected to electromagnetic force, and the long-term action will cause damage to the magnetic shield structure, coil deformation, and insulation damage. This article is about weakening the influence of structure electromagnetic force on the coupling mechanism of wireless power transmission system. First, analyze the structural electromagnetic force characteristics of the coupling mechanism of the wireless power transmission system from the perspective of frequency domain, and determine the relationship between the structural electromagnetic force characteristics and the phase of the current flowing through the coupling coil. Second, a structural electromagnetic force suppression scheme based on phase difference control is proposed. Using a two-wire parallel coupling structure, by adjusting the inductance of the adjustable branch connected in series to a certain transmitting coil branch, the phase of the current flowing through the coupling coil can be adjusted. Finally, the macroscopic force performance of the coupling mechanism is weakened. At the same time, an experimental platform was built to verify the effectiveness of the method.
