Compared with traditional contact wired power transfer technology, Wireless Power Transfer Technology (WPT) has the advantages of high security, flexibility, and reliability. However, in the process of static wireless power transfer in electric vehicles, the inaccuracy of manual parking can lead to the positional deviation between the transmitter and receiver, resulting in reduced power and efficiency of the system's power transfer, as well as system detuning and other issues. Therefore, it is expected that wireless power transfer systems can have a greater tolerance for position misalignment. Therefore, a new coupling machine with high misalignment tolerance is proposed in this article. The transmitter of this coupling mechanism consists of two double forward series flat solenoid coils(DSFS), and the receiver consists of a set of double D(DD) coils. Compared with traditional square and double D coils, the proposed new coupling mechanism improves misalignment tolerance in the x and y directions. This article first analyzes the characteristics and magnetic field distribution characteristics of the DSFS-DD coupling mechanism. Then, based on the constant voltage wireless power characteristics of electric vehicles, an LCC-S compensation network with constant voltage output characteristics was selected. Based on this, expressions for system output voltage, transfer efficiency, and output power are derived. To achieve stable system output voltage and power in the case of misalignment of the coupling mechanism, the coupling mechanism parameters were designed. Finally, simulation experiments are established to verify the effectiveness of the proposed method.
