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).

Hierarchical control strategies for islanded microgrids based on modular multilevel converters (MMCs)

2017 2nd International Conference on Power and Renewable Energy (ICPRE), 2017
This paper presents a hierarchical control strategy (HCS) for modular multilevel converter (MMC)-based islanded microgrid which is composed of two parts: the inner MMC control (IMC) and the outer loop control (OLC). The former includes the voltage and current control loops and the circulating current suppression algorithm, which are used to stabilize ...

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.

Control, design and power losses evaluation of a modular multilevel converter (MMC)

2019
This Master Thesis presents the design, control and power losses evaluation of a Modular Multilevel Converter (MMC). This converter has improved the competitive position of VSC-HVDC over LCC-HVDC due to its black-start capability, independent control of active and reactive power, and quality output waveform, and thereby allowing a reduction in the size
