Modelling and analysis of half‐/full‐bridge hybrid MMC when riding through DC‐side pole‐to‐ground fault

High Voltage, 2022
In a modular multilevel converter‐based high‐voltage direct current (MMC‐HVDC) system, the dc fault ride through (FRT) control is an effective way to deal with a dc‐side pole‐to‐ground (PTG) fault.

Fast DC Fault Current Suppression and Fault Ride-Through in Full-Bridge MMCs via Reverse SM Capacitor Discharge

Energies, 2022
In the event of a DC side fault in modular multilevel converters (MMCs), the fault current contributions are initially made by submodule (SM) capacitor discharge, which occurs before the fault is detected, followed by the AC side contribution to the DC ...
