【摘要】：目前四线圈结构无线能量传输系统大多采用磁谐振技术,通过调整实际负载与系统最佳负载相匹配实现系统最大效率工作。本文提出一种基于线圈回路复阻抗设计技术,可通过调整线圈回路复阻抗使得系统工作在最大效率状态。首先,对系统效率与各线圈回路复阻抗之间关系进行理论推导,证明基于线圈回路复阻抗设计技术的理论可行性。其次,采用数值仿真方法,分析理论推导与实际系统的差别,计算实际系统设计时线圈回路复阻抗数值,并对比两种最大效率设计方法的系统效率和功率输出性能;最后,搭建四线圈结构无线能量传输实验平台,对基于线圈回路复阻抗设计方法进行实验验证。
[Abstract]:At present, the magnetic resonance technique is used in the four-coil wireless energy transmission system, and the maximum efficiency of the system is realized by adjusting the actual load and matching the optimal load of the system. In this paper, a design technique based on complex impedance of coil loop is proposed, which can make the system work in the state of maximum efficiency by adjusting the complex impedance of the loop. Firstly, the relationship between the system efficiency and the complex impedance of each coil loop is deduced theoretically, and the theoretical feasibility of the complex impedance design technique based on the coil loop is proved. Secondly, the difference between the theoretical derivation and the actual system is analyzed by using the numerical simulation method, the complex impedance of the coil loop is calculated when the actual system is designed, and the system efficiency and the power output performance of the two maximum efficiency design methods are compared. A four-coil structure wireless energy transmission experimental platform was built to verify the complex impedance design method based on coil loop.
