USE OF THREE-PHASE CURRENT IN MOTIVE POWER UNITS

A Selbach

Open publisher page 0 citations

Abstract

The three-phase current propulsion technique has opened new perspectives for electric drive systems on board locomotives. Static inverters connected to power supply circuits compatible with the network allow the use of universal locomotives. The E 120 locomotive is a particularly striking example of this. The author describes the technology of the components used and initial results obtained with these locomotives and other vehicles as well as the extensive work required to perfect the technique. One of the main aspects dealt with is the economic advantages from the manufacturing and operating standpoint.
