Track supply

Inductive Power Transfer IPT®-Rail Generally the basic function of IPT® Rail systems is the same as that of other IPT® systems. But there are some additional or specific aspects to consider. Because vehicles are usually rail guided here and an elevated installation of the cable is possible it becomes also possible to use E-shape pickups. In applications with traveling track segments, i.e. switches in electric monorail systems, the experience with inductive power transfer can be used to supply such track segments inductively with energy. Wearing cable chain solutions or other similar solutions become second choice. If the idea of inductive power transfer is consequently realized it becomes even possible to feed so called safety zones in front of switches or lifts so that there is only power transfer possible when the segment is in position. To realize this no extra feeds or external control is necessary. Naturally IPT® can also replace other conventional solutions, as cable chains or conductor rails in skillet lines, skids or in transfer cars if there are certain requirements on the solution, for example if voltage arcs at rail ends shall be avoided or if the access for maintenance underneath skillet platforms is very limited. Track Supplies for IPT®-Rail Track Supplies do convert mains voltages of usually 50 or 60 Hz into a higher frequent output voltage. Usually IPT® systems are run at 15 or 20kHz. Only with this higher frequency of the output voltage and so the alternating magnetic field around the track cable an efficient non-contact power transfer becomes possible. Depending on the Regulators used on the secondary side track currents of 80 or 125 A are used.
