摘要
详细阐述了磁耦合谐振式无线能量传输技术的原理,建立了系统等效模型并分析得到系统传输效率公式,从而得出影响系统传输效率的因素,具体包括负载阻抗、系统频率、线圈线径、线圈半径、线圈匝数、线圈位置和传输距离。针对理论分析得到的各个影响因素,逐一仿真验证了它们对效率的影响效果,为提高磁场谐振耦合式无线能量传输系统的效率提供了理论依据。
The paper expounds principles of magnetically coupled resonant wireless power transfer(MCR-WPT). By equivalent model establishment and transfer efficiency equation conclusion through analysis, the influencing factors of system transfer efficiency such as load impedance, system frequency, coil diameter, radius, coil turns, position and transfer distance are obtained. The effect of influencing factors on efficiency from the theoretical analysis is simulated and verified to provide a reference for efficiency improvement of magnetically coupled resonant wireless power transfer system.
