A Novel Modular Expandable Multilevel Converter

International Journal of Circuit Theory and Applications
ABSTRACTMultilevel converters are widely used because of low harmonic content, low switching loss, and low electromagnetic interference. However, when the output voltage level of the traditional multilevel converter is high, it needs many power semiconductors and the control is complicated.

Comparative of modulation techniques for modular multilevel converter

IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015
The modulation technique chosen for use in the power converter largely defines the harmonics generated, consequently it is a fundamental part that must be studied. In this paper it's shown a comparative between different modulations techniques applied to a modular multilevel converter.

Performance of the modular multilevel converter with redundant submodules

IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015
The modular multilevel converter (MMC) is the state-of-the-art voltage-source converter (VSC) topology used for various power-conversion applications. In the MMC, submodule failures can occur due to various reasons. Therefore, additional submodules called the redundant submodules are included in the arms of the MMC to fulfill the fault-safe operation ...

Enhanced Equivalent Model of the Modular Multilevel Converter

IEEE Transactions on Power Delivery, 2015
This paper introduces an enhanced equivalent model of the half-bridge symmetrical monopole modular multilevel converter (MMC) topology for the analyses of the electromagnetic transients. Compared with the existing MMC models, the proposed model reduces the simulation computational time without compromising accuracy, and contrary to the existing models,

A distributed PWM strategy for modular multilevel converter

IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
The modular multilevel converter (MMC) has become a potential candidate for medium/high-power applications including high-voltage direct current (HVDC) transmission, adjustable speed drive, and static var compensation systems. One of the technical challenges associated with the control of an MMC is the choice of pulse width modulation (PWM) strategy ...

A simple control method for modular multilevel converters

2017 IEEE International Conference on Industrial Technology (ICIT), 2017
In this paper a simple control method involving new insertion index selection scheme for control of Modular Multilevel Converters (MMC) is proposed. In contrast with classical closed-loop methods, where all available arm voltages are measured and used in the generation process of insertion indices, this method uses available average voltage, i.e.
