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研究

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.
