Research on Energy Harvesting Method Without Blind Spots for a Two-dimensional Omni-directional Wireless Power Transfer System With Integrated LCC-S Topology
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.
