摘要/Abstract

摘要： 通过分析磁共振耦合系统在低频状态时的耦合系数、谐振频率、线圈内阻等因素对无线电能传输系统传输效率及输出功率的影响，建立了驱动线圈和负载线圈在非谐振状态下的补偿电容与输出功率、传输效率之间的关系，并推导出了优化的补偿电容的简化计算方法．试验结果表明，文中提出的方法在功率优化和效率优化方面是有效的．

关键词: 无线电能传输, 磁共振耦合, 补偿电容

Abstract:

In this paper,by analyzing the effects of coupling coefficient,resonant frequency and coil resistance on the transfer efficiency and output power of magnetically-resonant coupling system in low-frequency state,the relationship between the compensation capacitor of drive coil /load coil in non-resonant state and the output power as well as the transfer efficiency is established.In addition,a simplified calculation method of the optimized compensation capacitor is proposed.Experimental results show that the proposed method is adaptable and effective in power and efficiency optimization.

Key words: wireless power transfer, magnetically-resonant coupling, compensation capacitor
