资料介绍

提出一种基于双边LCC补偿的新型无线能量数据传输系统,具体介绍功率传输电路以及数据调制、发送、接收、解调电路的原理。详细介绍系统中每个元件的功能,总结系统设计的步骤,分析功率传输和数据传输之间的串扰以及减小干扰的设计规则。最后建立一个100W的样机。实际测量得到功率传输效率为90.5%,数据传输速率为119kbit/s,并且样机数据传输电路抗干扰能力强。在耦合系数降低60.2%的情况下依然能够正常工作,测量得到的功率传输与数据传输之间的干扰非常小,功率传输和数据传输几乎不受这些干扰的影响。

This paper proposes a novel wireless power and data transmission(WPDT)system using double-sided LCC compensation topology.The power transmission circuit and the modulation,injection,extraction,and demodulation circuits for data transfer are analyzed.The function of each component in the system is explained in detail.The specific steps of system design are summarized.The mutual interference between power transfer and data transfer and the design rules to reduce the interference are discussed.A 100W WPDT prototype is built.The practically measured power transfer efficiency is 90.5%,and the data transmission rate is 119 kbit/s.Data transmission can work well even though the coupling coefficient i...
