Abstract

Four coils magnetic resonant wireless power transmission system was constructed, and the efficiency model was established by using the theory of mutual inductance. The analysis of the maximum efficiency is based on two part factors, which are driving source and coils. The adjustment strategy of load coil and driving coil under the optimal efficiency was pointed out, which provided the theoretical guidance for the optimization of coil configuration mode and coil design. So the overall efficiency of the transmission system was improved effectively. At the same time, the experimental setup was built to test and analyze the change of efficiency under different transmission distance and different load resistance, and the correctness of theoretical analysis was verified. Based on the theoretical analysis, the maximum overall transmission efficiency of the experimental setup is 66.4%.
