Dual stage converters for multi-system high power locos. Architecture of loco E403

Abstract

Relationship between choices of power semiconductor devices and converter topologies are discussed, for multisystem locos. Advantages of dual-stage converter, associated to press-pack 4.5 kV IGBT are presented. Ansaldobreda phase-assembly for heavy railway is presented, as well as performances of power converter of E403 loco
