摘要

摘要: 建立了三线圈磁耦合谐振式无线电能传输系统的等效电路模型，推导出系统传输功率和传输效率公式，得出了系统在临界耦合状态下获得最大传输功率时的耦合因数关系，给出了耦合因数与频率分裂点之间的关系表达式，分析了系统频率特性。理论分析结果表明：在过耦合状态下，系统发生频率分裂现象，会出现3个频率分裂点；在临界耦合状态和欠耦合状态下，系统只在固有谐振频率处发生谐振；无论有没有发生频率分裂现象，系统均在固有谐振频率处发生谐振，此时系统传输功率达到最大。仿真和实验结果验证了理论分析的正确性。

Abstract: An equivalent circuit model of three-coil magnetic coupling resonant wireless power transmission system was built, and formulas of system transmission power and transmission efficiency were deduced. Coupling factors relation with the maximum system transmission power was obtained under critical coupling state, and relationship expression between coupling factor and frequency splitting point was given. Frequency characteristics of the system were analyzed. The theoretical analysis results show that there is frequency splitting phenomenon in the system under overcoupling state with three frequency splitting points; the system only resonates at inherent resonant frequency under critical coupling state and undercoupling state; whether there is frequency splitting phenomenon or not, the system resonates at inherent resonant frequency, and transmission power of the system reaches the maximum. The simulation and experimental results verify correctness of the theoretical analysis.
