Claim:
1. A system for transferring electric energy to a vehicle, comprising: the system comprises an electric conductor arrangement for producing an alternating electromagnetic field and for thereby transferring electromagnetic energy to the vehicle, the conductor arrangement comprises a plurality of consecutive segments, wherein each segment extends along a different section of the path of travel of the vehicle, the system comprises an alternating current supply for conducting electric energy to a plurality of the segments, wherein the segments are electrically connected in parallel to each other with the alternating current supply, each segment is coupled to the supply via an associated switching unit adapted to switch on and off the segment by connecting or disconnecting the segment to/from the supply, during operation of the segment while the switching unit is switched on, each segment is coupled to the supply via the associated switching unit and via a constant current source, the constant current source is coupled to the segment on one side and to the supply on the other side and is adapted to keep the electric current through the segment constant independently of the electric power which is transferred to one or more vehicles travelling along the segment, the alternating current supply is connected with an inverter which is conducted via the supply and through the constant current source of the segment during operation.
