近年来，电动汽车迅速普及，感应充电解决方案也随之普及。理想的固定充电系统不需要用户输入，并且对停车位置或环境条件（即下雨或下雪）的限制尽可能少。感应充电系统的成功很大程度上取决于磁耦合组件的设计;即跟踪板和拾取器。本文详细介绍了一种新的拓扑结构的轨迹板，由两个基本上共面，部分重叠的线圈定位，使它们之间没有互感。这种布置防止了两个线圈的相互作用，并且允许它们内的电流在相位和幅度上都是独立的。通过控制两个线圈电流的相位和幅度，可以对磁场进行整形，以帮助将电力传输到EV下方的拾取器。
Electric vehicles have been rapidly gaining in popularity in recent years, and with them inductive charging solutions. The ideal stationary charging system requires no input from the user, and places as few restrictions on either parking location, or environmental conditions (i.e. rain or snow) as possible. The success of inductive charging systems is contingent largely on the design of the magnetic coupling components; i.e. the track pad and the pickup. This paper details a new topology for the track pad, consisting of two largely coplanar, partially overlapping coils positioned such that there is no mutual inductance between them. This arrangement prevents interaction of the two coils, and allows the currents within them to be independent in both phase and magnitude. By controlling the phase and magnitude of the two coil currents, the magnetic field can be shaped to assist in power transfer to a pickup underneath an EV.
