Abstract: For the silicon based power devices in railway traction system are approaching their theoritical limit, the silicon carbide (SiC) power devices are expected to meet the needs for higher power density, lower loss and higher reliability of traction system. The recent advances in SiC MOSFETs, SiC SBD, hybrid SiC module and full-SiC module for railway traction is summarized. The development trends of SiC devices and modules for the future are also prospected. There some critical issues needed to be solved for SiC MOSFETs in terms of trench gate, integrated SBD, and fabrication processes of enhancing device reliability and electron mobility. And the studies of full-SiC devices, low stray inductance structure, low heat resistance base-plate and high relibility sintered layer are essential for SiC modules.

Key words: railwaytraction, SiC, MOSFET, full-SiCpowermodules
