High Power Factor Converters For Single-phase AC Traction Drives
Author(s)
A Bellini, S Bifaretti & S Constantini
Abstract
In the last years new power transistors, characterized by a high commutation speed, have been developed; these devices allows the employment of a closed loop current control for the four quadrants AC-DC converter used in high-speed traction locomotive with AC traction line. The paper shows two different structures for the converter and makes a comparison between their performances, underlining that a conversion structure composed by two series connected converters produces a better current harmonic content than a NPC inverter.
