Embodiment Construction
[0089] figure 1 Shows a conductor arrangement that may be located below ground along a track, for example, along a railroad track (see, for example, Figure 10 configuration shown). In the latter case, figure 1 The middle track runs from left to right. figure 1 The illustrated configuration may be one of multiple segments of the overall conductor configuration extending along the route of travel.
[0090] figure 1 It should be understood as a schematic diagram. figure 1 The illustrated conductor configuration is comprised between a first end portion 4a and a second end portion 4b ( figure 1 Three lines 1, 2, 3 extending from left to right or from right to left in the direction of travel). Each line includes sections extending transversely to the direction of travel. Only some of the laterally extending parts of the lines 1, 2, 3 are indicated with reference numerals, that is, the three parts 5a, 5b and 5c of the line 3, other parts of the line 3 are indicated with...

Abstract
The invention relates to a system for transferring electric energy to a vehicle (81; 92), in particular to a track bound vehicle such as a light rail vehicle, wherein the system comprises an electric conductor arrangement (12) for producing an alternating electromagnetic field and for thereby transferring the energy to the vehicle (81; ; 92), the electric conductor arrangement (12) comprises at least one alternating current line (1, 2, 3), wherein each alternating current line (1, 2, 3) is adapted to carry one phase of an alternating electric current, the conductor arrangement comprises a plurality of consecutive segments (T1, T2, T3, T4, T5), wherein the segments (T1, T2, T3, T4, T5) extend along the path of travel of the vehicle, each segment (T1, T2, T3, T4, T5) comprising one section of each of the at least one alternating current line, the system comprises a direct current supply line for supplying electric energy to the segments (T1, T2, T3, T4, T5), each segment is connected to the supply line via at least one inverter which is adapted to invert a direct current carried by the supply line to an alternating current carried by the at least one alternating current line.
Description
technical field [0001] The present invention relates to systems and methods for delivering electrical energy to vehicles, particularly rail vehicles such as light rail vehicles (eg, trams). Background technique [0002] In certain rail vehicles, such as conventional rail vehicles, monorail vehicles, tram buses and vehicles guided on rails by other means (e.g. by other mechanical, magnetic, electronic and / or optical means), Energy is required for propulsion on this track and to operate auxiliary systems that do not generate vehicle traction. Such auxiliary systems are, for example, lighting systems, heating and / or air conditioning systems, ventilation and passenger information systems. More specifically, however, the invention concerns the delivery of energy to a vehicle, which is not necessarily (but preferably) a rail vehicle. In general, the vehicle may be, for example, a vehicle with an electrically operated propulsion motor. The vehicle may also be a vehicle with a hy...
