Abstract
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.
