部分元等效电路理论在无线电能传输系统中的应用研究
Application of Partial Element Equivalent Circuit Theory in Wireless Power Transmission System
摘要
Abstract
The magnetic coupling resonant wireless power transmission technology has gradually become a hot issue in the field of wireless power transmission owing to its advantages such as a long transmission distance and a high transmission efficiency.However,the design and optimization of a magnetic coupling resonant system relies on the accurate calculations of parameters and system performance.In this paper,the partial element equivalent circuit(PEEC)method is proposed to solve these problems.First,the basic theory of PEEC and the calculation method for partial parameters are introduced.Then,a PEEC model of the coupling coil is established,and the self-inductance and mutual inductance of planar rectangular spiral coils are calculated.The calculation results are compared with experimental results to verify the efficiency and accuracy of the PEEC method.On this basis,a two-coil system and a single resonance magnetic coupling resonant wireless power transmission system are established,respectively,and the transmission characteristics of these two systems are studied and analyzed using the PEEC method combined with the circuit method.Moreover,the accuracy and rapidity of the proposed method were verified by comparing the calculated results with those obtained using the finite element method.关键词
