摘要
针对磁耦合谐振式无线电能传输系统存在负载特性差、传输效率低的问题,本文提出一种基于LCC-P(LCC-并联)型复合拓扑结构的磁耦合谐振式无线电能传输系统,利用电路理论和互感耦合理论计算出系统的传输效率和输出功率表达式,并给出参数配置方法。通过Matlab软件分析系统传输效率和输出功率随负载电阻、耦合系数、频率变化的三维关系图。最后利用PSIM进行相关实验验证,结果表明LCC-P型磁耦合谐振式无线电能传输系统的负载特性较好,频率特性一般,具有较高的输出功率和传输效率。
In order to solve the problem of poor load characteristics and low output power of magnetically-coupled resonant radio power transfer(MCR-WPT),a model of magnetically-coupled resonant radio power transmission system based on LCC-P complex topology is proposed in this paper. The circuit theory and mutual inductance coupling theory are used. The expression of the transmission efficiency and output power of the system is calculated,and the parameter configuration method is proposed. The three-dimensional relationship of transmission efficiency and output power with load resistance,coupling coefficient and frequency is analyzed by using Matlab software. Finally,PSIM software is used to verify the correlation,and the results of Matlab analysis are in good agreement. The results show that the LCC-P composite topology has high load characteristics,general frequency characteristics,high output power and transmission efficiency.
