摘要

动态无线电力传输（DWPT）是一项很有前途的技术，因为它减少了自动引导车辆携带的电池容量，降低了成本和重量。但在动态充电过程中存在较大的互感和功率波动。为了解决这一问题，本文提出了一种低成本、低波动的双接收机磁耦合器，由两个半桥整流器并联连接。变送器采用i型螺线管线圈，增强磁场，改善耦合。通过对耦合器结构的优化设计，使系统在动态充电过程中，通过两个接收线圈的相互切换，使系统具有平滑的互感波动。实验结果表明，测得的等效互感波动为3.6%，验证了磁耦合结构优化设计的可行性和所提DWPT系统的有效性。

A Smooth-Output Dynamic Wireless Charging System for Automated Guided Vehicles With Dual-Receiver Magnetic Coupler

Dynamic wireless power transmission (DWPT) is a promising technology as it reduces the battery capacity carried by automated guided vehicles and lowers its cost and weight. However, there are large mutual inductance and power fluctuation in the dynamic charging process. In order to solve this problem, this letter proposes a low-cost and low-fluctuation dual-receiver magnetic coupler, which is connected in parallel by two half-bridge rectifiers. The transmitter employs an I-type solenoid coil to enhance the magnetic field and improve the coupling. The optimized design of the coupler structure enables the system to have smooth mutual inductance fluctuation by switching the two receiving coils with each other during the dynamic charging process. The experimental results show that the measured equivalent mutual inductance fluctuation is 3.6%, which verifies the feasibility of the optimized design of the magnetic coupling structure and the effectiveness of the proposed DWPT system.

期刊介绍： The IEEE Transactions on Power Electronics journal covers all issues of widespread or generic interest to engineers who work in the field of power electronics. The Journal editors will enforce standards and a review policy equivalent to the IEEE Transactions, and only papers of high technical quality will be accepted. Papers which treat new and novel device, circuit or system issues which are of generic interest to power electronics engineers are published. Papers which are not within the scope of this Journal will be forwarded to the appropriate IEEE Journal or Transactions editors. Examples of papers which would be more appropriately published in other Journals or Transactions include: 1) Papers describing semiconductor or electron device physics. These papers would be more appropriate for the IEEE Transactions on Electron Devices. 2) Papers describing applications in specific areas: e.g., industry, instrumentation, utility power systems, aerospace, industrial electronics, etc. These papers would be more appropriate for the Transactions of the Society which is concerned with these applications. 3) Papers describing magnetic materials and magnetic device physics. These papers would be more appropriate for the IEEE Transactions on Magnetics. 4) Papers on machine theory. These papers would be more appropriate for the IEEE Transactions on Power Systems. While original papers of significant technical content will comprise the major portion of the Journal, tutorial papers and papers of historical value are also reviewed for publication.
