摘　　要：新型无接触电能传输系统利用电磁感应耦合技术与电力电子技术相结合,实现电能的无接触传输,消除了传统的电能传输方式带来的电击、短路和发生火花的危险。本文建立了新型无接触电能传输系统的数学模型,并分析研究了系统补偿拓扑、运行频率及负载参数对系统性能的影响。研究结果表明次级补偿可以大大提高系统的功率传输能力,而初级补偿则显著减小了对初级供电系统视在功率的要求,降低了系统成本。New contactless electrical energy transmission system realizes contactless power delivery to apparatus with no electrical connection or physical contact by the perfect combination of inductive coupling technique and power electronics, which eliminates the risk of electric shock, short circuit, or sparking. This paper establishes the mathematic model of this system, and investigates the effect of compensation topology, operational frequency, and load on system characteristics. Final results show that secondary compensation can improve the power transfer capability greatly, while primary compensation can reduce the required VA rating of the power supply obviously, which is a major system cost.
