The main purpose of Inductive Power Transmission (IPT) is efficient power transfer. Yet the ability to localize the receiver is itself an interesting goal. In Qi standards for wireless power transfer, the localization is performed by using a coils array. The resolution of localization is equal to the diameter of the coils in the transmitter array. Decreasing the diameter of coils in transmitters increases the resolution of localization but also reduces the range of power transfer. IPT is used in inductive RFID (Radio Frequency Identification) where a trade-off between resolution of localization and range of tag detection arises. This article proposes an original system making it possible to modify the resolution and the distance of operation independently. Calculations and simulations are implemented in MATLAB software. Experiments in low frequency validate the method and show the system capability to localize the receiver with good accuracy, with mean absolute error of 4 mm for localizing a receiver coil of 1 cm radius positioned in a box with dimensions 20*20*10 cm. Transmitter is a grid of 9 coils of 3.3 cm radius. After localization, the magnetic field is steered in the direction of the receiver to obtain a more efficient power transfer.

This paper discusses the history and research progress of wireless power transfer (WPT) for railway transportation. In the field of railway transportation traction power supply, the problems caused by the traditional contact‐type power supply method have become increasingly prominent: the overhead contact network prone to breakages, scraping and wearing the pantograph, etc. WPT technology, which avoids direct contact with the power supply sources and loads, effectively solves these problems. This paper focuses on the application of WPT technology for railway transit, and introduces the research status in China and abroad. Moreover, the main technologies and primary problems of WPT, including magnetic coupler, segmented power supply, design of high‐frequency inverter, system optimization and control and practical applications for trams, maglev vehicles, and high‐speed trains, are reviewed. A detailed analysis and summary on the technologies is also provided. By reviewing the state‐of‐the‐art development of WPT in railways, it is hoped that researchers could be encouraged by these achievements and pushed forward the further development in WPT. © 2018 Institute of Electrical Engineers of Japan.
