Abstract: The wireless power transfer (WPT) system is widely used for its convenience. However, how to address the problem of misalignment is a hard problem to solve. This paper proposes a design method for an output-parallel Series-Series (SS) WPT system based on a designed splitting coil coupler. The method aims to optimize the parameters of coil structure based on the multi-island genetic algorithm. Besides, by designing splitting coils and specific parameters, the performance of misalignment tolerance of multi-channel coils is improved, and the detailed analysis is proposed as well. Finally, A 3.3kW splitting coil WPT system prototype is built. Compared to the traditional design, the proposed design can achieve a higher coupling with the same misalignment distance, as well as less power loss by the designed splitting coils.
