Abstract

This paper presents the influence of distance, resonance frequency and constructive aspects of the coils for Wireless Power Transfer (WPT), showing the best configuration according to the needs of the application, especially for the automotive battery charging, situation factors such as the distance between the emitter and the receiver, the size of the coil used and alignment make implementation difficult. The behavior between the coils includes wire turns, along with other coils of several wire turns, and is simulated computationally and analyzed to verify what is the better performance. The results are presented for resonance frequencies varying between 100kHz and 1MHz, spacing from 1 to 180cm, showing the behavior of the efficiency curve for application in electric vehicles. Five different configurations are addressed by varying, in addition to the number of turns, the diameters of the coil wires. Simulations of yield curves are compared with experimental results to validate the reliability of the calculation.

用于电动汽车的无线传输系统性能分析

本文介绍了距离、谐振频率和线圈结构对无线电力传输(WPT)的影响，并根据应用的需要给出了最佳配置，特别是在汽车电池充电中，发射极与接收器之间的距离、线圈的尺寸和对准等情况因素使实现变得困难。线圈之间的行为包括线圈匝数以及其他线圈匝数，并进行了模拟计算和分析，以验证哪种线圈的性能更好。给出了谐振频率在100kHz ~ 1MHz范围内，间距在1 ~ 180cm范围内的结果，显示了应用于电动汽车的效率曲线的行为。五种不同的配置是通过改变，除了匝数，直径线圈电线。仿真结果与实验结果进行了比较，验证了计算的可靠性。
