| 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. |
