A system for transferring electric energy to a vehicle such as a track bound vehicle or road automobile. The system includes an electric conductor arrangement which produces an alternating electromagnetic field, transfers electromagnetic energy to the vehicle and includes a plurality of segments. Each segment extends along the vehicle path of travel and includes one line for each phase of alternating current carried by the segment. The system includes a current supply for conducting electric energy to the segments which are electrically connected in parallel. At least one segment is coupled to the current supply via a constant current source. Each constant current source includes one or more inductances and one or more capacitances, the inductances and capacitances being adapted to each other and the input side of the constant current source so that a constant current is output to the output side.

System and method for transferring electric energy to a vehicle using constant current operation of segments of a conductor arrangement

The invention relates to an arrangement for providing a vehicle, in particular a track bound vehicle, with electric energy, wherein the arrangement comprises a receiving device () adapted to receive an alternating electromagnetic field and to produce an alternating electric current by electromagnetic induction. The receiving device () comprises a plurality of windings and/or coils () of electrically conducting material, wherein each winding or coil () is adapted to produce a separate phase of the alternating electric current.

Inductively receiving electric energy for a vehicle

The invention relates to a system for transferring electric energy to a track bound vehicle, in particular to a light rail vehicle, such as a tram, wherein the system comprises an electric conductor arrangement () for producing an electromagnetic field and for thereby transferring the energy to the vehicle, the electric conductor arrangement () comprises at least one line () for carrying one phase of an alternating voltage or current, the line () extends along the track, the line () is arranged in such a manner that it produces&#x2014;at each point in time while the alternating electric current is flowing through the line ()&#x2014;a row of successive magnetic poles (at sections) of an electromagnetic field, wherein the successive magnetic poles have alternating magnetic polarities, the row of successive magnetic poles extends in the travel direction of the vehicle which is defined by the track.

Transferring electric energy to a vehicle

The invention is a system for transferring electric energy to a vehicle. The system includes an electric conductor arrangement for producing an alternating electromagnetic field and for thereby transferring the energy to the vehicle. The electric conductor arrangement includes at least one alternating current line, wherein each alternating current line carries one phase of an alternating electric current. The conductor arrangement includes a plurality of consecutive segments, wherein the segments extend along the path of travel of the vehicle. Each segment includes one section of each of the at least one alternating current line. The system also includes a direct current supply line for supplying electric energy to the segments. Each segment is connected to the supply line via at least one inverter which inverts a direct current carried by the supply line to an alternating current carried by the at least one alternating current line.
