Prospects and Challenges of 4H-SiC Thyristors in Protection of HB-MMC-VSC-HVDC Converters

Pole-to-pole DC faults on HB-MMC-VSC-HVDC schemes impose significant risk of cascade failure on IGBT/diode pairs. Other novel topologies with fault blocking capability, i.e. AAC converters, and DC circuit breakers are not yet fully matured. Therefore, silicon thyristors are used to bypass the DC fau...
