磁耦合谐振无线输电系统不同拓扑结构的分析

摘要/Abstract

摘要：

无线输电系统中,工作频率和距离是主要的输入变量,而较高的输出功率和传输效率是目标。对于磁耦合谐振无线输电系统,输入变量与目标的关系取决于磁耦合谐振无线输电系统的拓扑结构,磁耦合谐振无线输电系统的拓扑结构可分为串串结构、串并结构、并串结构和并并结构,本文应用等效电路方法对这四种拓扑结构进行了详细的分析,得到了输出功率和传输效率的表达式,研究了功率和效率关于频率、距离的关系,并进行了比较。通过研究和仿真分析发现,在谐振频率点附近四种拓扑结构的系统均达到最优匹配,并且得到了最佳传输距离。还证明了系统最大传输效率只与接收端电路结构有关,与发射端电路结构没有必然联系。本文还制作了串并结构的实验模型,验证了理论分析和仿真结论的正确性。

Abstract:

The man input variables in the wireless power transmission (WPT) system are the working frequency and the transmission distance while the goal is to obtain high output power and transmission efficiency. For WPT systems based on magnetic coupling resonance (MCR), the relations between input variables and the target depend on the topology. Using the method of equivalent circuit to analyze, in detail, four topological structures applied in MCR-based WPT systems-serial-serial (SS) structure, serial-parallel (SP) structure, parallel-serial (PS) structure and parallel-parallel (PP) structure -this paper obtains the expressions to calculate the output power and the transmission efficiency, studies and compares relations of the power and efficiency versus frequency and distance. It is found from theoretical study and simulation analysis that all of these four topological structures reach the optimal matching around the resonant frequency, and subsequently the best transmission distance is obtained. It is also proved that the maximum transmission efficiency of the system is associated with the structure of the circuit at the receiving end and has no necessary link with the structure of the circuit at the transmitting end. This paper also presents an experiment using the serial-parallel structure which has demonstrated that the result from both theoretical analysis and simulation are correct.
