摘要：
In the wireless power transfer system, the misalignment of transmitting and receiving coils is inevitable, which reduces the coupling coefficient and efficiency of the coils. However, the existing coils, such as double D (DD), have good misalignment tolerance in only one direction. In order to solve this problem, a quadruple D square coil with high misalignment tolerance in multi directions is proposed. Firstly, the magnetic coupling structure of the coil is studied, and the theoretical expression of the mutual inductance of the QDS coil is derived. Then the JMAG software was used to simulate square coils, DD coils, QD coils and QDS coils. By analyzing the magnetic flux density distribution characteristics and misalignment characteristics of the coils, it is proved that QDS coils have strong anti-offset ability. Finally, a platform was built to measure the mutual inductance when the coil was offset, and the advantages of the QDS coil were verified by comparison and analysis with the square coil, DD coil and QD coil. © 2022 Chinese Machine Press.
