Outlook for SiC devices in traction converters
2012 Electrical Systems for Aircraft, Railway and Ship Propulsion, 2012Silicon (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.

Converters based on IGCTs in light traction drives
IEEE 2002 28th Annual Conference of the Industrial Electronics Society. IECON 02, 2003So far, the integrated gate-commutated thyristor (IGCT) has always been considered as a device suitable for converters controlling the power of the order of megawatts or higher. This paper shows how the advantages of the device can be used in a DC chopper and in an inverter designed to feed the traction motors of a trolleybus.
