With the development of the dynamic wireless power transfer (DWPT) technology, the influence of the coils relative speed on circuit response is attracting increasing attention. However, due to the starting and braking processes of moving vehicles, the straight-track experimental platform requires the installation of additional transmitter coils to simulate higher speeds. This design will inevitably occupy too much installation space. To address the above limitations and simulate fast-moving DWPT systems within a limited space, a design scheme for the circular experimental platform is proposed in this paper. Additionally, to ensure device reliability and minimize eddy current loss, the rotation radius, magnetic coupler, and information communication of the experimental platform are considered and designed. Then, a DWPT circular experimental platform, which could satisfy the simulation requirements for speeds up to 200 km/h, is constructed, and its circuit responses are tested under different speed conditions.
