摘　　要：针对磁耦合谐振无线电能传输(MCRWPT)系统中负载接入数目对于系统整体输出功率与传输效率的影响问题,设计了一种带有中继线圈的多载接入式MCR WPT系统,通过控制系统中负载线圈的接入数目,研究系统的输出功率与传输效率的变化。当系统中接入负载数目增加时,单个负载的传输效率与传输功率逐渐下降,但系统总的输出功率与传输效率逐渐上升,并随着负载数目增加至8个以后,系统的输出功率与传输效率达到饱和,饱和点系统的输出功率为4.51 W,传输效率为79.12%。Aiming at the influence problem of the number of load connections in the magnetic coupling resonant wire-less power transmission(MCR WPT)system on the overall output power and transmission efficiency of the system,a multi-load access MCR WPT system with a repeating coil is designed.By controlling the number of loads in the sys-tem,the output power and transmission efficiency of the system are studied.When the number of connected loads in the system increases,the transmission efficiency and transmission power of a single load gradually decrease,but the total output power and transmission efficiency of the system gradually increase,and as the number of loads increases to 8,the output power and transmission efficiency of the system reach saturation,the output power of the saturation point system is 4.51 W,and the transmission efficiency is 79.12%.
