Optimum Efficiency Analysis of Wireless Power Transfer System via Coupled Magnetic Resonances with Lateral and Angular Misalignments
摘要
Abstract
Transmission efficiency will be reduced when transmission and receiving coils are aligned non-coaxially in the wireless power transfer system (WPT) via coupled magnetic resonances.The expression for the efficiency of the WPT system was derived by coupled-model theory (CMT).The variation rule of the transmission efficiency was analyzed according to this expression.In this paper,the method of adjusting parameters based on chaos optimization algorithm was proposed.Then key parameters of the WPT system can be matched.It is shown the efficiency can be improved by the proposed method.A wireless power transmission system via magnetic resonance coupling was designed.Simulation and experimental results have verified the theory.关键词
