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

摘要

Disclosed is a system for inductively transferring electric energy to a vehicle (81) using an electric conductor arrangement for producing an alternating electromagnetic field and for thereby transferring the energy to the vehicle (81). The conductor arrangement comprises a plurality of consecutive segments (T1, T2, T3) extending in the direction of travel of the vehicle (81), which is defined by the track (83) or path of travel. Each segment (T1, T2, T3) is combined with an assigned controller adapted to control the operation of the segment (T1, T2, T3) independently of the other segments (T1, T2, T3). The controllers of at least two consecutive segments (T1, T2, T3), which follow each other in the direction of travel of the vehicle (81), or which follow each other opposite to the direction of travel, are connected to each other and/or to a central controlling device so that the at least two consecutive segments (T1, T2, T3) can be operated at the same time. Each segment (T1, T2, T3) comprises at least three alternating current lines for carrying phases of a multi-phase alternating current in order to produce the alternating electromagnetic field. The consecutive segments (T1, T2, T3) are electrically connected in parallel to each other to a current supply. The alternating current lines of each segment (T1, T2, T3) comprise a plurality of sections which extend transversely to the direction of travel of the vehicle (81). The transversely extending sections of the at least three alternating current lines of each segment (T1, T2, T3) form, if viewed in the direction of travel, a repeating sequence of phases of the alternating current, while the segment (T1, T2, T3) is operated under control of the assigned controller. Each complete repetition of the sequence of phases comprises one transversely extending section of each phase and the order of the phases is the same in each complete repetition. The controllers of the at least two consecutive segments (T1, T2, T3) and/or the central controlling device are/is adapted to operate the at least two consecutive segments (T1, T2, T3) so that the repeating sequence of phases continues from one segment (T2) to the consecutive segment (T3) and the order of the phases is the same in the at least two consecutive segments (T1, T2, T3) and in each transition zone of two of the at least two consecutive segments (T1, T2, T3).
