The delta configured modular multilevel converter
2016 IEEE Power and Energy Society General Meeting (PESGM), 2016The modular multilevel converter (MMC) has become an attractive option for dc/ac conversion in many power system applications, in particular, for HVDC transmission. Due to its parallel arrangement of phase legs, the MMC is known to be a wye-configured architecture.

Capacitor selection for modular multilevel converter
2014 IEEE Energy Conversion Congress and Exposition (ECCE), 2014Submodule (SM) capacitor is a key component in a modular multilevel converter (MMC), the selection of which must consider the component’s specifications and the requirements of the targeted converter application. This paper focuses on the capacitor selection for MMCs in applications including high-voltage direct current (HVDC) transmission and static ...

Modular multilevel converter models for electromagnetic transients
2014 IEEE PES General Meeting | Conference & Exposition, 2014Modular multilevel converters (MMCs) may contain numerous IGBTs. The modeling of such converters for electromagnetic transient type (EMT-type) simulations is complex. Detailed models used in MMC-HVDC simulations may require very large computing times. Simplified and averaged models have been proposed in the past to overcome this problem.

Submodule capacitor dimensioning for Modular Multilevel Converters
2012 IEEE Energy Conversion Congress and Exposition (ECCE), 2012This paper deals with the dimensioning of the capacitors in modular multilevel converters based on analytical equations. Considered design parameters are the (periodic) energy fluctuation, the admissible ripple voltage, and the demand in control reserve. Design examples complete this paper.

Multisampling in interleaved converters and modular multilevel converters
IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016This paper presents a method for sampling the analog variables and running the controller in multi-cell converters with a frequency higher than the switching frequency. First we introduce the multi-cell converters and highlight their similarities. Next we describe the devised method and explain the strategy to avoid simultaneous sampling and switching ...

The Multilevel Modular DC Converter
IEEE Transactions on Power Electronics, 2013The modular multilevel converter (M2C) has become an increasingly important topology in medium- and high-voltage applications. A limitation is that it relies on positive and negative half-cycles of the ac output voltage waveform to achieve charge balance on the submodule capacitors.

Capacitor monitoring for modular multilevel converters
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017The modular multilevel converter (MMC) is attractive for medium-or high-power applications because of the advantages of its high modularity, availability, and high power quality. Reliability is one of the most important challenges for the MMC consisting of a large number of submodules (SMs).
