Modular multilevel converter composite submodule topology and control

Modular multilevel converter composite submodule topology and control

The DC-side short-circuit fault suppression of modular multilevel converter (MMC) applied to DC transmission has been a technical problem. According to the different location of cutting off fault current, this study first analyses three possible suppression schemes: AC/DC circuit breaker, bridge arm...
