Abstract

Taking maximum power transmission and power stable transmission as research objectives, optimal design for the wireless power transmission system based on magnetic resonance coupling is carried out in this paper. Firstly, based on the mutual coupling model, mathematical expressions of optimal coupling coefficients for the maximum power transmission target are deduced. Whereafter, methods of enhancing power transmission stability based on parameters optimal design are investigated. It is found that the sensitivity of the load power to the transmission parameters can be reduced and the power transmission stability can be enhanced by improving the system resonance frequency or coupling coefficient between the driving/pick-up coil and the transmission/receiving coil. Experiment results are well conformed to the theoretical analysis conclusions.

摘要

本文以最大功率传输和功率稳定传输为研究目标，对基于磁共振耦合的无线功率传输系统进行了优化设计。首先，基于互耦模型，推导了最大功率传输目标下最优耦合系数的数学表达式。随后，研究了基于参数优化设计提高功率传输稳定性的方法。研究发现，通过提高系统谐振频率或驱动/拾取线圈与传输/接收线圈之间的耦合系数，可以降低负载功率对传输参数的敏感度，增强功率传输稳定性。实验结果与理论分析结论吻合良好。
