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.
