Improved hybrid modular multilevel converters with dc short-circuit fault ride-through capacity

Modular multilevel converter (MMC) has become a promising converter alternative for transmission voltage-source converter high-voltage direct current applications. The main issue and challenge of MMC is how to handle the dc short-circuit fault. Based on the half-bridge MMC, this study proposed an im...
