Pulse converters in traction applications

Power Engineering Journal, 1994
After over a century of electric traction, the virtual monopoly of the commutator motor is drawing to a close. Major advances in devices and techniques have made the application of polyphase induction motors to traction units a viable proposition. The authors describe how the use of pulse power converters in these units can improve the electrical ...

Investigation of the propagation of harmonic distortion from traction converters into traction and transmission systems

2006 IEEE Power Engineering Society General Meeting, 2006
Modern locomotives that utilize pulse-width modulated power converters produce harmonics that propagate along the traction system and ultimately into the transmission system. This paper investigates the occurrence of this in a traction system in Central Queensland, Australia.

Outlook for SiC devices in traction converters

2012 Electrical Systems for Aircraft, Railway and Ship Propulsion, 2012
Silicon (Si) IGBTs are widely used in railway traction converters. In the near future, Silicon Carbide (SiC) technology will push the limits of switching devices in the three directions: higher blocking voltage, higher operating temperature and higher switching speed.
