Improved core shape of contacless transformer for LRT system

The crescent interest in greener transportation systems increases the search for coherent, intelligent, efficient and more cost effective solutions. In this scenarios Light Rail Transits are becoming more and more used. In the direction or more flexible and safer system, contactless power systems are being used in LRT. This paper present an Improved core shape for the contactless transformer used in a model LRT system. The electrical and the magnetic analysis of the transformer are performed and compared to a Planar core transformer. The Improved core allows to suppress the utilization of core in the secondary reducing the weight in the train car with keeping the required transmitting power and input voltage.
