Abstract
This paper describes an optimized design of secondary coils in the inductive power transfer (IPT) system for railway vehicles. The gap between the primary and secondary coils is large, and the weight of the on-board secondary coil needs to be reduced. Thus, we propose a design method of dimensions of the secondary coils and unique cross-section of the secondary coils to improve the induced voltage and to reduce the self-inductance of the secondary coil. Further, practical issues that arise when applying the design to the railways, for example, human exposure to time-varying electric and magnetic fields, are examined.
