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.

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 ...
