摘要:
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.

A system for transferring electric energy to a vehicle, in particular to a track bound vehicle such as a light rail vehicle, includes an electric conductor arrangement for producing an alternating electromagnetic field and for thereby transferring electromagnetic energy to the vehicle. The vehicle includes at least one receiver for receiving the electromagnetic energy and at least one signal transmitter adapted to repeatedly or continuously emit an enable signal towards the track. The vehicle also includes a transmitter control arrangement adapted to stop transmitting the enable signal if the receiver or if any device combined with the receiver is not to be operated.

An arrangement for providing a plurality of vehicles, in particular track bound vehicles, with electric energy, includes an electric conductor arrangement for producing alternating electromagnetic fields and for thereby transferring electromagnetic energy to the vehicles. The conductor arrangement includes a plurality of consecutive segments, wherein each segment comprises at least one phase line for carrying a phase of an alternating current. Corresponding phase lines of neighbouring consecutive segments are connected in series to each other. The arrangement further includes a direct current power supply line for supplying electric energy to the segments. A switching device for producing the alternating current of the conductor arrangement from the current carried by the, power supply line is connected to each interface between two neighbouring consecutive segments. The arrangement also includes a control device for controlling the operation of the switching devices.

A system for transferring electric energy to a vehicle. The system comprises an electric conductor arrangement which produces an alternating electromagnetic field, transfers electromagnetic energy to the vehicle, and includes a plurality of consecutive segments. Each segment extends along the path of travel of the vehicle. The system includes an alternating current supply for conducting electric energy to the segments which 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. Each segment is coupled to the associated switching unit via a constant current source adapted to keep the electric current through the segment constant while the segment is switched on independently of the electric power which is transferred to one or more vehicles.
