Patent

CA 2736977

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.

Système de transfert dénergie électrique à un véhicule (81; 92), notamment un véhicule ferroviaire tel quun véhicule léger sur rail, le système comprenant un agencement de conducteurs électriques (12) destiné à produire un champ électromagnétique alternatif et à transférer lénergie au véhicule (81; 92), lagencement de conducteurs électriques (120) comprenant au moins une ligne à courant alternatif (1, 2, 3), chaque ligne à courant alternatif (1, 2, 3) étant conçue pour porter une phase dun courant électrique alternatif. Lagencement de conducteurs électriques comprend une pluralité de segments consécutifs (T1, T2, T3, T4, T5), les segments (T1, T2, T3, T4, T5) suivant une trajectoire du véhicule, chaque segment (T1, T2, T3, T4, T5) comprenant un tronçon de la ou de chaque ligne à courant alternatif. Le système comprend une ligne dalimentation en courant continu destinée à alimenter les segments (T1, T2, T3, T4, T5) en énergie électrique, chaque segment étant relié à la ligne dalimentation par au moins un onduleur conçu pour convertir un courant continu porté par la ligne dalimentation en un courant alternatif porté par la ou chaque ligne à courant alternatif.
