SiC‐based high‐gain DC–DC converters with fault ride‐through capability [PDF]
IET Power Electronics, 2020 This study presents active switched passive network‐based high‐gain DC–DC converters. The active switched network is formulated using two inductors, one capacitor and two diodes. Hence, the network is named as a 2L–C–2D network. Using ten components, an asymmetric high‐gain DC‐DC converter is proposed.

Precharging and DC Fault Ride-Through of Hybrid MMC-Based HVDC Systems [PDF]
IEEE Transactions on Power Delivery, 2015 Compared to half-bridge based MMCs, full-bridge based systems have the advantage of blocking dc fault, but at the expense of increased power semiconductors and power losses. In view of the relationships among ac/dc voltages and currents in full-bridge based MMC with the negative voltage state, this paper provides a detailed analysis on the link between
