摘要 针对无线电能传输系统在发射侧和接收侧偏移时输出功率和传输效率降低的问题,该文从共享磁通的角度提出了基于LCC拓扑的反极性同心式补偿电感集成方法,并提出了两种集成结构。建立了基于多耦合工作模式和线圈品质因数的反极性同心式无线电能传输系统输出功率和传输效率的数学模型,从数学模型上验证了集成式结构的抗偏移能力,仿真结果显示集成式结构在正对和偏移情况下,其磁通密度均优于非集成式结构。搭建了补偿电感集成式结构的实验样机,实验结果表明,补偿电感集成式结构在一定的偏移范围内能保持稳定的传输效率和输出功率,在相同输入电压和传输距离下比非集成式结构具有更高的传输效率和更大的传输功率。

Abstract:A method for integrating a reversed-polarity concentric compensating inductor based on the LCC topology is proposed from the perspective of shared flux, then two integrated structures are proposed. A mathematical model of the output power and transmission efficiency of the reversed-polarity concentric wireless power transmission system based on the multi-coupling mode of operation and the quality factor of the coil is developed, and the offset resistance of the integrated structure is verified from the mathematical model. The simulation results show that the integrated structure outperforms the non-integrated structure in terms of flux density in both forward and offset cases. The experimental prototype of the compensated inductor integrated structure is built. The experimental results show that the compensated inductor integrated structure can maintain stable transmission efficiency and output power within a certain offset range, and has higher transmission efficiency and higher transmission power than the non-integrated structure at the same input voltage and transmission distance.
