摘要
基于近场磁耦合的谐振式无线供电(wireless power transmission,WPT)系统因其可在中等传输距离内实现高效能量传输而成为当前科学与工程技术领域研究的热点。主要研究采用电磁场一体化建模及其全波数值分析方法对该类WPT系统的分析与设计,应用矩量法(method of moment,MoM)并考虑该系统的实际应用环境,基于一体化精确建模实现WPT的精确快速仿真。此外,还基于该方法研究了WPT系统的应用环境对系统性能的影响,尤其针对电动汽车底盘式无线供电环境,研究地面对WPT性能的影响,并提出该环境下WPT的使用建议。最后,应用该算法进行了WPT环境一体化设计,提出一种含电磁屏蔽结构的高效WPT结构。
The wireless power transmission system based on near field magnetic coupling is a research topic in scientific and industry for it can achieve middle-range power transmission with high efficiency.This work focues on the electromagnetic unitary model and full wave simulation method by method of moment,by which the affection of applied environment will be considered and the fast and accurate simulation approach will be achieved.After that,this approach will be used to analyze the affection of the environment on the performance of WPT.Specially,the influence of chassis on the WPT performance in application of electricity vehicle wireless power is studied.At last,this approach is applied to design a new WPT with a shield structure.
