To enhance the flexibility of installation of wireless power transfer (WPT) system on railway vehicles, we modified the WPT system to increase the power per unit opposing area of ground and onboard coil up to 150 kW/m2 by setting the mechanical gap between coils at 150-mm. In this paper, we describe the design of the improved WPT system capable of collecting 150 kW with a single onboard coil and the results of bench test using a reduced model to verify the system.
