| 摘 要： | 无线电能传输效率的优化具有重要研究意义,无线充电系统中存在着系统最佳阻抗。充电过程中,电池阻抗并非在最佳阻抗点,传输效率偏低。为了实现效率的优化,将LCC-S型拓扑结构与DC-DC变换器结合,实现宽范围调节的阻抗匹配。首先从理论分析了最佳阻抗点的数值,然后通过仿真软件MATLAB验证了效率的提升与宽范围的调节,最后搭建了无线电能传输的实验平台。实验表明,加入阻抗匹配的系统传输效率达到83%以上,证了上述方案的正确性与可行性。

| Abstract: | Improvement of wireless power transmission efficiency has great research significance,an optimum resistance exists in wireless power system.During charging process,battery resistance is not at the optimum load point and the system efficiency is low.In order to improve the efficiency of the whole system,combination of LCC compensation structure and DC-DC converter achieves resistance matching with wide range adjustment.At first,the figure of the optimal resistance point is analyzed by theory,then the efficiency improvement and wide range adjustment are verified by MATLAB.Lastly,mental platform with wireless power system is built.Experiments show that the system efficiency with load resistance matching,demonstrating feasibility of above. |
