Abstract

Wireless power transmission systems via inductive link provide nowadays an interesting option for charging devices wirelessly. The power transmission can be realized by using a couple of coils placed in proximity of each other. These coils may differ in their materials, technology, and geometries. In this paper, an investigation of different flexible coils geometries has been carried out. In fact, we investigate circular, square hexagonal and octagonal shapes with similar design parameters such as an internal radius of 2.4 cm, an external radius of 4 cm and six turns. The coils comparison is based on the measurement of the self-inductances and quality factors of the coils in different situations, such as number of used coils sides, damping and ideal states. The results show a similar behavior of the singular and dual-sided coils. The highest coil’s quality factor was in the case of a circular coil shape, whereas the highest self-inductance was in the case of a square coil shape. The coil with circular shape shows the lowest self-inductance and quality factor variation in the case of maximum coil damping.

感应输电系统柔性线圈几何结构研究

通过感应链路的无线电力传输系统为当今的无线充电设备提供了一个有趣的选择。电力传输可以通过使用彼此靠近的一对线圈来实现。这些线圈可能在材料、技术和几何形状上有所不同。本文对不同几何形状的柔性线圈进行了研究。事实上，我们研究了具有相似设计参数的圆形、方形、六角形和八角形，如内半径为2.4厘米，外半径为4厘米和6转。线圈的比较是基于测量线圈在不同情况下的自感和质量因素，如线圈的使用边数、阻尼和理想状态。结果表明，单面线圈和双面线圈具有相似的特性。最高线圈的质量因子是在圆形线圈形状的情况下，而最高的自感是在方形线圈形状的情况下。当线圈阻尼最大时，圆形线圈的自感和质量因子变化最小。
