Abstract
A system for transferring electric energy to a vehicle, including an electric conductor arrangement for producing an alternating electromagnetic field and for thereby transferring electric energy to a vehicle. The conductor arrangement includes a plurality of consecutive segments. Each segment is combined with an assigned controller adapted to control the operation of the segment independently of the other segments. The controllers of at least two consecutive segments are connected to each other and/or to a central controlling device so that the at least two consecutive segments can operate at the same time. Each segment includes at least three alternating current lines for carrying phases of a multi-phase alternating current. The consecutive segments are electrically connected in parallel to each other to a current supply. The alternating current lines of each segment include a plurality of sections which extend transversely to the direction of travel of the vehicle.
