摘要：在無線電能傳輸系統(tǒng)中，維持高效率和高功率的同時，會導(dǎo)致系統(tǒng)的漏磁大幅升高。提出了一種應(yīng)用于無人機無線電能傳輸系統(tǒng)的多線圈發(fā)射系統(tǒng)，該系統(tǒng)在保證傳輸效率和輸出功率的同時減小目標觀測面上的漏磁大小。基于一種計算方形線圈磁場密度的方法，提出了磁場編輯技術(shù)，運用該技術(shù)可以改變目標位置的磁場強度；結(jié)合磁場編輯算法與改進型粒子群算法，使控制部分能夠較大維度去控制該系統(tǒng)；提出了多發(fā)射線圈陣列的無人機無線充電系統(tǒng)，通過仿真分析可知，當系統(tǒng)輸出功率恒定在200 W 時，該系統(tǒng)使目標區(qū)域最大泄漏維持在 5μT 且傳輸效率高達96.7%。

Abstract: Maintaining high efficiency and power in a wireless power transfer system can lead to a significant increase in the magnetic flux leakage of the system. For this reason the paper proposes a multi-coil transmitting system applied to unmanned aerial vehicle (UAV) wireless power transfer system, which reduces the magnitude of magnetic flux leakage on the target observation surface while maintaining the transmission efficiency and output power. Firstly, based on a method for calculating the magnetic field density of a square coil and proposes a magnetic field editing technique, which can be utilized to change the magnetic field strength at the target location. Secondly, the magnetic field editing algorithm is combined with an improved particle swarm algorithm to enable the control section to control the system in a larger dimension. Finally, a wireless charging system for UAVs with multiple transmitting coil arrays is proposed, and the simulation analysis shows that the proposed system maintains the maximum leakage in the target area at 5 μT and the transmission efficiency is as high as 96.7% when the output power of the system is kept at a constant level of 200 W.

Key words: wireless power transfer; particle swarm algorithm; magnetic field editing
