摘　　要：无线电能传输系统主要包括逆变环节、补偿拓扑、耦合器、整流环节四部分。实际中系统的补偿元器件出厂前已被确定,但负载变化和耦合器偏移都会影响整个系统的谐振状态,间接降低传输效率。本文提出一种新型的三线圈IPT系统的耦合器,采用在接收线圈增加反串联线圈的结构,通过maxwell 3D软件仿真验证该结构线圈在耦合器发生水平、旋转偏移时,耦合器自身参数,如自感、互感的变化率相比传统两线圈结构有明显的提升。另外,本文在通过传统两极板仿真时,得出了耦合器的自身参数受哪些变量的影响,方便读者后续工艺设计,并给出了比较适配的极板参数范围,以提供参考价值。Wireless power transfer system comprises four main components:an inverter module,compensation topology,coupler,and rectifier module.While the compensation components of the system are predetermined before delivery,variation in load and misalignment of the coupler can have a detrimental effect on the overall resonance state,thus indirectly reduce the transmission efficiency.This paper proposes a novel coupler design for a three-coil IPT system.It incorporates an additional anti-series coil in the receiving coil structure.Through simulation using Maxwell 3D software,it is demonstrated that this modified coil structure exhibits a significant improvement in self-inductance and mutual inductance compared to the traditional two-coil structure when horizontal and rotational misalignment of the coupler occurs.Furthermore,this paper outlines the factors that influence its parameters of the coupler during conventional two-plate simulations,facilitating subsequent process design,and provides a range of plate parameters suitable for comparison and reference purposes.
