摘要:
      随着电场耦合电能传输(ECPT)系统功率和传输距离的提高,系统耦合机构极板上的电压也会不断增大,给周围环境带来漏电场辐射问题。针对耦合机构漏电场抑制问题,文中提出了一种新型的层叠式耦合机构。在对新型层叠式耦合机构进行建模分析的基础上,以双侧LC补偿网络的ECPT系统为例,推导了极板电压的计算表达式。对耦合机构外侧极板电压的主要影响因素进行分析,提出了一种以抑制系统漏电场为目标并兼顾系统传输性能的系统参数设计方法。通过仿真,验证了所提出的耦合机构及参数设计方法对漏电场抑制的可行性和有效性。
Abstract:
      As the transmission power and distance of electric-field coupled power transfer(ECPT)systems increase, the plate voltage of the coupler will also increase, which brings the radiation of fringing electric field in the surrounding environment. This paper proposes a novel four-plate coupler to suppress the fringing electric field. Based on the modelling and analysis of the novel four-plate coupler, formulas of the voltage on four plates are derived by taking a double-sided LC-compensated ECPT system as an example. Moreover, the main affecting factors of the voltage on outer plates are analyzed, and a system parameter design method considering the transmission performances of the system is provided to suppress the fringing electric field. The validity of the proposed coupler and the design method has been confirmed by the simulation results.
