Power balancing in multi-converter systems composed of modular multilevel converters (MMCs)
2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe), 2016Multi-converter systems composed of series or parallel connected modular multilevel converters (MMCs) require a means to manage power sharing between the MMCs by balancing the load during operation. Series connected MMCs require proper voltage balancing while parallel connected MMCs require proper current balancing.

A novel voltage balancing method of Modular Multilevel Converter (MMC)
2011 International Conference on Energy, Automation and Signal, 2011The main problem in the new potential Modular Multilevel converter (MMC) topology for high and medium level is the voltage balancing of the capacitors of their sub modules. The novel balancing technique which is introduced in this paper based on sorting of the capacitor voltages. After sorting and detection of the arm current direction, neither require

Optimal Control of Modular MultiLevel Converters (MMCs) for Minimum Storage Requirement
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018With the push towards Medium Voltage DC (MVDC) based electrical distribution systems, the power converter(s) between Medium Voltage AC generators and common MVDC buses must handle more power than any other electrical power conversion component in the distribution system. The Modular Multi-Level Converter (MMC) is a compelling topology for this function

Protecting modular multilevel converters (MMC) against ac fault by deadbeat control
2013 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2013The paper shows that deadbeat control and harmonic elimination by feedforward and feedback can be implemented by MMC. In tracking the current reference, MMC is: (i) safe from large destructive of ac faults; (ii) free from the odd harmonics generated by the nonlinearities of MMC. As deadbeat control cannot filter the even harmonics on the dc side, their
