“…The operating principle of the TAMBC is different from the SM-based SCC topologies, since only two arms generate the output voltage and the remaining two arms are bypassed via the thyristor path. Also, the TAMBC has a lower total energy deviation, hence a lower capacitive energy storage requirement per MVA [64].…”

“…Thyristors are broadly applied in some of the topologies, since they can offer significantly lower losses compared to the full-controlled devices such as IGBT and IGCT. The introduction of thyristor valves in the AT-AAC and TAMBC reduces the conduction losses of SMs [36], [64]. Additional single SM voltage (SSMV), dual SM voltage (DSMV) and hybrid SM voltage (HSMV) control methods can be used for decreasing the power losses and the size of thyristor snubber circuits [88], [89].…”

The unique advantages of modular multilevel converters (MMCs) have led to wide adoption of the converter topology in high voltage dc (HVDC) transmission systems, with great potential for use in medium voltage motor drive and dc grid applications. Inspired by the structure of the MMC, many extended converter topologies have been developed in the literature. These include, in addition to conventional parallel multiphase connection, a variety of series-connected topologies. Extended MMCs integrate the modular nature of cascaded SMs of the MMC but with different topology structure leading to substantially different operating principles. Given the growing number of such topologies, this paper provides a critical review of MMC derived topologies and summarizes individual advantages and disadvantages. The control schemes * : Common characteristics and advantages/disadvantages of the whole category.
