N2 - Dynamic wireless power transfer (DWPT) breaks the dependence of power supply on fixed locations and physical connections. It enables continuous and stable energy replenishment during equipment movement and holds great promise. Traditional magnetic coupler suffer from large mutual inductance fluctuations. To solve this issue, this paper proposes a novel magnetic coupler. Based on a single-pole long coil guide rail type, an overlapping design is employed to suppress mutual inductance fluctuations in transmitter. A single-layer DDQ structure is designed to compensate for mutual inductance drops when the Q coil is misaligned. Furthermore, finite element analysis (FEA) is performed on the parameters of the magnetic coupler, elucidating the influence of parameters on mutual inductance fluctuations, providing a technical reference for the further development of DWPT for electric vehicles (EV).
