Contactless transformer is the key part of the inductive power transfer (IPT) system that can realize safe electric-energy supply for mobile devices. This paper proposes a novel contactless transformer structure with trapezoidal magnet core, which can be applied to movable vehicle such as high-speed maglev vehicle IPT system. The inductances of primary and secondary windings of different core structures...
EMS (Electromagnetic Suspension) type Maglev vehicles like HSST (High Speed Surface Transport) that use linear induction motors for its thrust system have been in the stage of practical application. With medium and low speed, they are ideal mode for urban mass transit. But many inhabitants living near the Maglev line are concerned about the environment impact. In this paper, the leakage magnetic field...
