Comprehensive understanding of DC pole-to-pole fault and its protection for modular multilevel converters

A modular multilevel converter (MMC) is one of the promising voltage source converter topologies in the field of high-voltage direct current (HVDC) transmission. MMCs are vulnerable to the direct current (DC) short-circuit faults due to the high discharge current stress. This study first introduced...
