摘　　要：感应耦合供电(ICPT)技术为旋转结构供电提供了安全高效的解决方案,针对旋转结构传统的侧置式和同轴式感应耦合供电结构存在耦合结构设计、安装、调试繁琐的缺点,提出了一种感应耦合供电的平面阵列线圈结构。通过建立精确三维有限元模型,分析了移动中系统供电的稳定性和抗偏移性。实验结果表明,该耦合结构消除了传统结构供电时发射与接收线圈位置保持相对静止的弊端,对运动物体供电具有良好的鲁棒性和可移植性,易于安装和使用,更好地适应移动设备供电。提取阵列线圈结构感应供电时接收线圈感应电压幅值的小幅波动,可以同时实现转轴转速测量。Inductive coupled power transfer(ICPT)technology provides a safe and efficient solution for power supplying of rotating structures.For the disadvantages of design installation and debugging in traditional coaxial and side-mounted structure,this paper presents a planar array coil inductive coupled power transfer structure.It analyzes the stability and offset resistance of the power supply in the mobile system by building the 3 D FEM model.The experimental results show that the coupling structure eliminates the disadvantages of the position of the transmitting and receiving coils being relatively static when the traditional structure is powered.It has good robustness and portability to the moving object.It is easy to install and use,and better adapts to the power supply of mobile devices.When this structure is powered,the speed of the rotating shaft can be acquired at the same time by the small fluctuation of the induced voltage amplitude in receiving coil.
