Enhanced Equivalent Model of the Modular Multilevel Converter
IEEE Transactions on Power Delivery, 2015This 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,

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.

A distributed PWM strategy for modular multilevel converter
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014The 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), 2017In 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.

Frequency-domain modeling of modular multilevel converters
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012Modular multilevel converters (MMC), based on cascading of half-bridge converter cells, can combine low switching frequency with low harmonic interference. They can be designed for high operating voltages without direct series connection of semiconductor elements.

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.
