摘要

提出了一种多发射机线圈无线电力传输系统,消除了由于发射机线圈过耦合而产生的分频效应。为了消除发射机产生的磁场分裂,提出在发射机阵列中使用不同尺寸的线圈。这是通过设计三种不同的多线圈发射器阵列来实现的,每个发射器阵列有五个发射器线圈,其中一个接收器线圈放置在距离发射器40厘米的地方。第一个阵列用相同尺寸的线圈设计。第二个和第三个阵列被设计成较小尺寸的线圈放置在较大尺寸的线圈之间。通过考虑接收线圈处的散射参数,比较了三种阵列的性能。结果表明,在较大的线圈之间使用较小的线圈尺寸会导致多发射机阵列中的均匀耦合,从而抑制并随后消除接收信号的分频现象。

Frequency Splitting Elimination in a multi-coil power transfer system
A multiple transmitter coil wireless power transfer system that eliminates the frequency splitting effect as a result of overcoupling between very close transmitter coils is proposed. The use of coils of different sizes in the transmitter array is proposed in order to eliminate the splitting of the magnetic field produced by the transmitters. This is done by designing three different multi-coil transmitter arrays, each with five transmitter coils with a single receiver coil placed 40 cm from the transmitters. The first array is designed with coils of the same size. The second and third arrays are designed with coils of smaller sizes placed between larger size coils. The performance of the three arrays is compared by considering the scattering parameters at the receiver coil. It is shown that using smaller coil sizes between larger coils causes uniform coupling in the multiple transmitter array, resulting in suppression and subsequent elimination of the frequency splitting phenomenon of the received signal.

期刊介绍: Remote Sensing Information is a bimonthly academic journal supervised by the Ministry of Natural Resources of the People's Republic of China and sponsored by China Academy of Surveying and Mapping Science. Since its inception in 1986, it has been one of the authoritative journals in the field of remote sensing in China.In 2014, it was recognised as one of the first batch of national academic journals, and was awarded the honours of Core Journals of China Science Citation Database, Chinese Core Journals, and Core Journals of Science and Technology of China. The journal won the Excellence Award (First Prize) of the National Excellent Surveying, Mapping and Geographic Information Journal Award in 2011 and 2017 respectively. Remote Sensing Information is dedicated to reporting the cutting-edge theoretical and applied results of remote sensing science and technology, promoting academic exchanges at home and abroad, and promoting the application of remote sensing science and technology and industrial development. The journal adheres to the principles of openness, fairness and professionalism, abides by the anonymous review system of peer experts, and has good social credibility. The main columns include Review, Theoretical Research, Innovative Applications, Special Reports, International News, Famous Experts' Forum, Geographic National Condition Monitoring, etc., covering various fields such as surveying and mapping, forestry, agriculture, geology, meteorology, ocean, environment, national defence and so on. Remote Sensing Information aims to provide a high-level academic exchange platform for experts and scholars in the field of remote sensing at home and abroad, to enhance academic influence, and to play a role in promoting and supporting the protection of natural resources, green technology innovation, and the construction of ecological civilisation.
