文章摘要
在磁耦合谐振无线电能传输研究中,采用何种线圈结构能使传输距离达到最远目前还没有一个定论。根据毕奥-萨伐尔定律理论推导了矩形、平面型和圆柱型等三种螺旋线圈的空间磁场分布表达式;提出一种求解磁场空间分布的新算法,并对结果进行了验证。绘出三种线圈在最大半径、匝间距及匝数一致时的空间分布三维图;比较三种不同结构线圈的空间磁场分布规律,为无线电能传输研究中采取何种结构线圈作为系统发送、接收线圈提供理论参考。
Abstract
In the research of magnetic resonance coupling wireless power transmission, there is no conclusion of what kind of coil configuration enables the farthest transmission distance currently. According to the Biot Savart law theory, three kinds of expressions in the spatial magnetic field about spiral coil are given, which are rectangular, planar and cylindrical. Besides, a new algorithm for solving the magnetic field spatial distribution is presented, and the results are verified, and the 3D spatial distribution of three coils are plotted at their maximum radius and at the circumstance of turns getting the same. Finally the magnetic field distribution of three kinds of different structures of coil are compared. This study is able to provide theoretical reference for which coil should be adopted as the system receiving and delivering coil in the study of the wireless power transmission.
