Reflexive properties for different pick-up circuit topologies in a distributed IPT track

The paper deals with the dynamic charging of the electric vehicles by an inductive power transfer (IPT) system with a segmented track. The reflexive properties of the IPT system is studied by evaluating the reactance of a transmitting coil when coupled with a pick-up with respect to uncoupled conditions. Different topologies for the pick-up circuit are evaluated, some of them introduced in this paper, with the aim of finding out the topology that offers the best reflexive properties. The impact of the different topologies on the IPT system efficiency performance is also argued.
