摘要
针对二维全向无线电能传输技术存在空间磁场完整度与电流控制策略复杂度的竞争问题,该文提出一种集成LCC-S 拓扑的二维全向无线电能传输系统无盲区能量捕获方法.该系统以二维正交线圈为电磁耦合机构,并将其集成于 LCC-S 型补偿拓扑.同时提出一种自调整参数设计方法,实现系统在二维空间内产生时均旋转磁场以及系统的零相角输入.通过场-路耦合有限元模型分析系统在二维空间内磁场分布情况,随时间峰值磁场强度矢量轨迹为圆形.搭建集成型二维全向无线电能传输的实验样机,实验结果表明,该系统实现单一电源驱动下无盲区的二维全向电磁能量捕获.
Abstract
This paper proposes a method for capturing wireless power in a two-dimensional omnidirectional manner without blind spots by integrating the LCC-S topology.The approach addresses the competition between spatial magnetic field integrity and the complexity of current control strategies in two-dimensional omnidirectional wireless power transfer technology.The system uses two-dimensional orthogonal coils as electromagnetic coupling mechanisms and integrates them into the LCC-S compensation topology.Additionally,the paper presents a system parameter design condition and a self-adjusting parameter adjustment strategy to achieve the system's production of an evenly rotating magnetic field in two-dimensional space and a zero-phase angle(ZPA)input.The magnetic field distribution in the system in two-dimensional space is analyzed by using a field-road coupling finite element model,and the peak magnetic field intensity vector trajectory over time is circular.An integrated two-dimensional omnidirectional wireless power transfer experimental prototype is constructed,and experimental results demonstrate that the system achieves two-dimensional omnidirectional electromagnetic energy capture without blind spots under a single power source drive.
