摘要:
磁共振式无线能量传输技术因传输距离较远、效率较高而成为研究热点。文章对四线圈结构的磁共振式无线能量传输系统进行建模,并利用互感耦合模型对系统传输效率进行分析,提出一种逐级分析方法,清晰展现线圈间能量传递关系,推导出内阻、失谐因子、强耦合系数是影响系统传输效率的重要因素。在几种特定应用场景基础上,设计了一种新型的PCB磁共振线圈系统,对所提出的分析方法进行了验证,为后期优化设计提供了依据。
Abstract:
Magnetic resonance wireless power transmission technology has become a research focuse due to its characteristic of far distance and high efficiency. Four-coil magnetic resonant wireless power transmission system model was presented and the system transmission efficiency was analyzed by mutual inductance coupling circuit models. Putting forward a step by step analysis method, it clearly showed the relationship of energy transfer efficiency between coils. Resistance, detuning factor and coupling coefficient factor have been derived as important factors affecting transmission efficiency. On the basis of several application scenarios, a new type of PCB magnetic resonance coil system was designed. The above analysis was verified, which could provide a basis for the later optimization design.
