Abstract Multiple-receiving coupling coils mode can reduce the design difficulty for high power wireless power transfer systems, such as reducing the stress of the device, but the characteristics of such model need to be analyzed in detail. In this paper, one-to-one coupling coils model and multi-receiving coupling coils model are compared under the constraints of the same output power and load, and the relationships between the number of the multi-receiving coupling coils and the system parameters, such as mutual inductance, frequency, load and efficiency are analyzed by fixed variable method. In addition, in the multiple-receiving coupling coils mode, the system parameters of the single load and the multi load are compared and analyzed, the advantages of the multi-receiving coupling coils in improving system efficiency are demonstrated. Finally, the experimental results are given to prove that the mode of multi-receiving coupling coils has a certain effect on improving the system efficiency.
