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), 2016
Multi-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, 2011
The 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
