摘要：
为了解决磁耦合方式无线电能传输技术在金属障碍环境下因涡流效应而效率低下问题，该文开展了金属障碍环境下超声无线电能传输技术研究。首先从声学的角度分析能量传输通道参数对声波透射系数的影响规律，并指导完成通道参数的配置。然后，采用同时共轭阻抗匹配技术完成通道输入端口与输出端口的阻抗匹配网络设计，并通过实验验证阻抗匹配网络的有效性。测试结果表明，该文所设计的超声波无线电能传输系统透11 mm厚304不锈钢障碍的理论最佳传输效率为68%，进行同时共轭阻抗匹配后通道的实际能量传输效率为56.25%，传输功率达51.53 W。该研究所达到的能量传输效率和传输功率均能满足绝大部分使用需求。该技术在军事、航天等领域具有较好的应用前景。

Abstract: In order to solve the problem of inefficiency of wireless power transmission technology by magnetic coupling method in metal obstacle environment due to eddy current effect, this paper carries out the research of ultrasonic wireless power transmission technology in metal obstacle environment. Firstly, the influence of the energy transmission channel parameters on the acoustic transmission coefficient is analysed from the acoustic point of view, and the configuration of the channel parameters is guided to be completed. Then, the simultaneous conjugate impedance matching technique was used to complete the design of the impedance matching network for the channel input port and output port, and the effectiveness of the impedance matching network was verified through experiments. The test results show that the theoretical optimum transmission efficiency of the ultrasonic wireless power transmission system designed in this paper is 68% through 11 mm thick 304 stainless steel barriers, and the actual energy transmission efficiency of the channel after simultaneous conjugate impedance matching is 56.25%, and the transmission power reaches 51.53 W. The energy transmission efficiency and transmission power achieved by the system can meet most of the usage requirements. The technology has broad application prospects in military and aerospace fields.
