Inductively transferring electric energy to a vehicle using consecutive segments which are operated at the same time

Abstract

The invention relates to an arrangement () for transferring electric energy to a vehicle, in particular to a track bound vehicle such as a light rail vehicle () or to a road automobile, wherein—the arrangement () comprises an electric conductor arrangement () for producing an alternating electromagnetic field and for thereby transferring the energy, —the conductor arrangement () comprises a plurality of consecutive segments (T, T, T, T, T), wherein the segments (T, T, T, T, T) extend in the direction of travel of the vehicle, —each of the consecutive segments (T, T, T, T, T) comprises at least one alternating current line () for carrying a phase of an alternating current in order to produce the alternating electromagnetic field, —each of the consecutive segments (T, T, T, T, T) is combined with an assigned controller (CTR) adapted to control the operation of the segment (T, T, T, T, T) independently of the other segments (T, T, T, T, T), —at least two neighbouring segments () of the consecutive segments (T, T, T, T, T) are inductively coupled to each other so that a first segment () of the neighbouring segments (), while the first segment () is operated under control of its assigned controller (CTR), induces a voltage and thereby produces an induced alternating electric current in a second segment () of the neighbouring segments (), if the second segment () is not operated under control of its assigned controller (CTR), —the arrangement () comprises a controllable coupling (S) for coupling the second segment () to a load (RL; F, S), which controllable coupling (S) has a first operating state in which the second segment () is coupled to the load (RL; F, S) so that any alternating electric current in the second segment () is damped by the load (RL; F, S), and has a second operating state in which the second segment () is not coupled to the load (RL; F, S) so that any alternating electric current in the second segment () is not damped by the load (F, S), —the arrangement () is adapted to switch the controllable coupling (S) to the first operating state before, while and/or after a time interval starts in which the second segment () is not operated under control of its assigned controller (CTR) and in which the first segment () is operated under control of its assigned controller (CTR) so that the induced alternating electric current in the second segment (), which is produced by operation of the first segment (), is damped by the load (F, S).
