“…There is a third switching state: both switches are off during startup or fault conditions, allowing the current to freely circulate through the diodes (and through capacitors, if so demanded by the current polarity) [1,34]. In practical application, there is an additional bypass switch to fully isolate each cell for fault-tolerant operation [39]. An important problem is the control needed to keep each capacitor in constant cell voltage level [36].…”

“…An attractive feature of this topology is its modularity and scalability to easily reach medium-and high-voltage levels, while greatly improving AC side power quality, as compared with the classic series connection of power switches in a two-level converter configuration used in HVDC [1,34]. This topology can be found in practical applications reported with 200 power-cell/phase reaching up to 400 MW [39] and is commercialized by ABB and Siemens as HVDC Light up to 1 GW [5][6].…”

“…(8) and (9), the number of submodules required for the investigated star switched modular multilevel converter is 50% of that which would be required for the standard MMC for a similar application, ignoring switching effects. Considering that one of the two arms in each phase of the star switched MMC is only responsible for switching conduction from one arm to the other and only sees the line voltage, the number of devices required for the SSMMC can be obtained from (10) and that of the MMC from (11). (10) and (11), the theoretical savings on the number of devices for using the SSMMC can be derived to be 32% of that required for the implementation of the MMC.…”

“…Recently, the Modular Multi-Level Converter (MMC) [1,3,11,12] has been proposed and is being extensively investigated for HVDC applications. It offers some interesting characteristics including, high modularity, scalability, high converter efficiency, low device stress, low loss, and reduced harmonic content in the synthesised waveform.…”

“…В 2010 году первая линия HVDC на базе ММС связала города Питтсбург и Лос-Анджелес (Trans Bay Cable). Протяженность кабельной ли-нии составила 88 км, передаваемая мощность -400 МВт, передача электроэнергии осуществля-лась на напряжении ±200 кВ [9]. Каждая фазная ветвь модульного многоуровневого преобразова-теля включала порядка 200 модульных ячеек.…”
