Application is being considered of a contactless power supply system to battery-run or hybrid trains. The system has many potential advantages compared with normal (contact) power supply systems. The contactless system eliminates the danger of electric shocks or leaks and is low-noise and has maintenance-free features, however, the energy transmission through space tends to reduce energy supply efficiency and increases the cost of the equipment. This paper reports on coil configurations aimed at overcoming these problems.
