摘要

多线圈感应电力传输系统在工业、医疗和智能家居应用中越来越重要。在接收机横向不对准甚至位置可变的情况下,它们对实现功率传输非常有用。为了减少能量损耗,对接收机的检测和在其下的发送线圈的供电策略提出了很高的要求。本文提出了一种基于测量发送线圈电压幅值的位置检测方法。为了研究新型探测器的可靠性,将接收线圈存在时测量的电压幅值与不同金属材料存在时的电压幅值进行了比较。测量是在同轴和不对准的接收器位置下进行的。实验结果证明了该方法对不同位置和尺寸的接收线圈检测的有效性。它区别于接收线圈和导电目标材料之间的高可靠性。

Passive Peak Voltage Sensor for Multiple Sending Coils Inductive Power Transmission System
Multi-coil inductive power transmission systems become more and more important in industrial, medical and smart home applications. They are very useful to realize power transmission in case of receivers having some lateral misalignment or even a variable position. In order to reduce losses of energy, a receiver detection and a powering strategy of the sending coils under it is highly required. In this paper, a position detection method is proposed, which is based on the measurement of the voltage amplitude of the sending coils. To investigate the reliability of the novel detector, the measured voltage amplitude in presence of the receiving coil is compared to the voltage amplitude in presence of different metallic materials. The measurements have been carried out under co-concentric and misaligned receiver positions. Experimental results prove the efficiency of the proposed method to detect the receiver coil with various positions and sizes. It differentiates with a high reliability between a receiver coil and a conductive target material.
