摘要
分析比较各种无线电能传输方案,选用电磁共振原理进行无线电能传输;分析影响无线电能传输效率、传输功率、传输距离的因素,设计改进相关电路并进行实验验证;给出实验验证后的系统方框图,设计多个发射输出级,以微处理器为控制核心,运行设定的程序,比较各发射输出级供电电流的大小,从而从某一输出端输出一定频率的脉冲信号,以此控制哪一个发射输出级单独供电,提高了电源利用率,提高了传输效率。
The paper analyzes and compares various radio transmission schemes in which wireless power is transmitted through electromagnetic resonance principle,provides the advice on improving related circuit and being tested by experiment by analyzing the factors influencing radio energy transmission efficiency,transmission power,transmission distance. It also thinks after the system block diagram is tested by experiment,multiple emission output prots with microprocessor control core operating setting procedures are designed,supply current level of various emission output port are compared,and one emission output port is controlled to supply singly power by outputting a fixed frequency pulse signal from certain output port. As a result,the utilization rate and transmission efficiency of power are improved.
