摘要

路面嵌入线圈是一种不同于静态无线传输系统的动态无线传输系统。污染很容易进入线圈之间的路面。因此，有必要明确污染对DWPT效率的影响。用LCR仪对线圈参数和理论效率进行了评价。并通过动力传输实验对WPT系统的效率进行了评价。铁砂是道路施工中的有效污染物，影响线圈参数，导致最大效率降低0.14%。残留的海水和雨水使交流效率分别降低0.93%和0.6%。此外，残留的水改变了系统的共振频率。

Influence of Contamination Between Receiver Coil and Embedded Transmitter Coil for Dynamic Wireless Power Transfer System

Embedded coils into road pavement are applied to dynamic wireless power transfer (DWPT) that coil arrangement is different from static WPT system. Contamination easily enters the road pavement between the coils. Therefore, it is necessary to clarify the effect of contamination on the efficiency of DWPT. Coil parameters and theoretical efficiency have been evaluated by an LCR meter. Furthermore, WPT system efficiency has been evaluated by a power transmission experiment. Iron sand, which is the effective contamination in road construction, affects coil parameters causing a 0.14% reduction of maximum efficiency. Moreover, remained seawater and rainwater decrease the AC-to-AC efficiency by 0.93% and 0.6%, respectively. In addition, remained waters change the resonance frequency of the system.
