Reliability-oriented switching frequency analysis for Modular Multilevel Converter (MMC)

2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015
In this paper, reliability-oriented switching frequency analysis for Modular Multilevel Converter is investigated. In the medium voltage and high voltage direct current applications, the switching frequency should be low enough to avoid the converter from high switching power losses.

Systematic modeling and control of indirect modular multilevel converter (MMC) with grid unbalance estimation

IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013
Modular multilevel converter (MMC) is considered as an idea and promising candidate for multilevel technology. By connecting two MMCs in back-to-back configuration with a DC transmission cable, a so-called indirect MMC can be constructed for high-voltage direct current transmission application.

A novel capacitor voltage balancing control strategy for modular multilevel converters (MMC)

2013 International Conference on Electrical Machines and Systems (ICEMS), 2013
Recently modular multilevel converters are highly attractive for medium, high-voltage power transition and electrical machine drive. Capacitor voltage sorting is very important for capacitor voltage-balancing control. This paper describes a novel sorting algorithm for capacitor voltage of modular multilevel converters (MMC).

An improved circuit topology of modular multilevel converter (MMC) for DC to AC applications

2016 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2016
This paper proposes a new circuit topology of MMC for DC to AC applications. The main advantage of the proposed topology is the elimination of lower arms of conventional MMC. Additionally, the DC bus voltage magnitude is half compared to conventional MMC. This is achieved by replacing the lower arms of conventional MMC topology with LC filter.

A novel SVPWM technique for capacitor voltage balancing in modular multilevel converters(MMCs)

2017 11th IEEE International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG), 2017
This paper proposes a novel space vector pulse width modulation (SVPWM) technique to address the capacitor voltage balancing issue in MMCs. The MMC topology consists of cascade connected identical and individual controllable submodules (SMs) to generate higher level output voltages.
