System for inductively transferring electric energy to a vehicle using consecutive segments

摘要

Disclosed is a system for transferring electric energy to a vehicle (81), in particular to a track bound vehicle such as a light rail vehicle or to a road automobile. The system comprises an electric conductor arrangement for producing an alternating electromagnetic field and for thereby transferring the energy to the vehicle (81). The conductor arrangement comprises a plurality of consecutive segments (T1, T2, T3) which extend along the path of travel of the vehicle (81). Each segment (T1, T2, T3) includes at least one alternating current line for carrying an alternating current in order to produce the alternating electromagnetic field. The system includes a current supply (108) for supplying electrical energy to the segments (T1, T2, T3),. The segments are electrically connected in parallel to each other and to the current supply (108). For a sequence of consecutive segments, (K1, K2, K3) is assigned and connected to each segment (T1, T2, T3). Each assigned converter (K1, K2, K3) is connected to the current supply (108) and is adapted to convert a current carried by the current supply (108) to an alternating current carried by the at least one alternating current line of the segment (T1, T2, T3) so that there is a sequence of assigned converters (K1, K2, K3) for the corresponding sequence of consecutive segments (T1, T2, T3). Each of the sequence of assigned converters (K1, K2, K3) is connected to a synchronisation link for synchronizing operation of the sequence of assigned converters (K1, K2, K3). The system is adapted to synchronise the sequence of assigned converters (K1, K2, K3) in a manner so that the electromagnetic field produced by the sequence of consecutive segments is continuous at the interface or interfaces between the consecutive segments (T1, T2, T3).
