摘要

针对双拾取无线电能传输系统的系统功率分配问题，利用阻抗分析方法分析了LCL-S型拓扑结构下系统功率以及系统效率的影响因素，并提出一种在满足负载功率需求条件下的系统效率最优的功率分配策略。该控制策略根据系统负载功率和耦合机构互感优化拾取端的功率分配，实现功率传输和效率的优化控制。最后，通过仿真与实验验证了理论分析的正确性。

Abstract

For the power distribution problem of wireless power transfer(WPT)system with dual-pickup coils

the LCL-S topology is chosen as compensation topology of the system. This paper analyzes the influence factors of power and efficiency of the system by adopting the impedance analysis method. Moreover

a power distribution strategy of optimal system efficiency is given under the condition of meeting the demand of power load. The control strategy optimizes the power distribution of pick-up port based on the system load power and mutual inductance of coupler

and realizes optimal control of the power transmission and system efficiency. Finally

the correctness of the theoretical analysis is verified by simulation and experiment.
