Wireless power transmission technology can be a simple and frequent high power, such as 300kW, charging measure to the energy storage device onboard railway vehicle. In this application, higher reactive power should be cared due to the long gap between primary coil and secondary coil on the coils design. Switching loss of the power converters should be looked after by the less switching frequency and zero current switching (ZCS) technologies. In this paper, the author introduces the design method of the coils with less reactive power and presents one of experimental results of a power control method with ZCS technologies by means of scale down experimental model.
