Modular multilevel converter (MMC) is widely used in medium to high power applications.
One of the significant features that an MMC can provide is the fault tolerant operation, which …

Hot reserved redundant sub-modules significantly increase the reliability of MMC systems
equipped with considerable sub-modules. This paper presents a fault-tolerant operation …

Modular multilevel converter (MMC) is an attractive topology for medium-and high-voltage
applications due to the merits of high modularity, easy scalability, high-quality output …

In this thesis work, fault tolerant control and operation of a Modular Multilevel Converter
(MMC) has been investigated. The MMC consists of multiple Sub Modules (SM). The MMC …

The modular multilevel converters become more and more popular in high power
applications in recent years. The solution to make the MMC operate well under the …

In addition to its modular nature, a Hybrid Modular Multilevel Converter (HMMC) assembled
from half-bridge and full-bridge sub-modules, is able to block DC faults with a minimum …

Each arm of modular multilevel converter (MMC) consists of a large number of sub-module
(SM) units. However, it also increases the probability of SM failure during the long-term …

Conventional three-phase MMC consists of six-arms, each arm is controlled to generate
unipolar voltage ranging from zero to Vdc where Vdc is the input DC voltage. Each arm …

In this paper a new post fault operation strategy is proposed for modular multilevel converter
(MMC). The conventional MMC fault tolerant operation methods use redundant cells in …

A modular multilevel converter (MMC) is considered to be a promising topology for medium-
or high-power applications. However, a significantly increased amount of sub-modules …
