Distributed Control for the Modular Multilevel Matrix Converter

IEEE Transactions on Power Electronics, 2019
The modular multilevel matrix converter (M3C) is a direct ac/ac topology and is promising in the medium-voltage high-power application. However, the current M3C prototypes mainly adopt the centralized control structure that may hinder its modularity and flexibility.

Model Predictive Control of Modular Multilevel Matrix Converter

2015 IEEE 24th International Symposium on Industrial Electronics (ISIE), 2015
This paper presents a new and simple Finite Control Set Model Predictive Control (FCS-MPC) strategy of the Modular Multilevel Matrix Converter (M3C). This converter is one of the direct AC/AC power converters suitable for medium-voltage high-power machine drives with regenerative capacity. One of the main feature of this converter is that does not need

Arm Inductance Quantification for Y-Matrix Modulated Modular Multilevel Converter

2020 IEEE 9th International Power Electronics and Motion Control Conference (IPEMC2020-ECCE Asia), 2020
Y-Matrix Modulated (YMM) Modular Multilevel Converter (MMC) was proposed recently. This modulation utilizes the self-voltage balancing capability of an MMC so that the conventional voltage balancing algorithm of MMC can be eliminated. YMM demonstrates that MMC has inherent self-voltage balancing capability.

Low output frequency operation of modular multilevel matrix converter

2015 5th International Conference on Electric Utility Deregulation and Restructuring and Power Technologies (DRPT), 2015
When the multilevel modular matrix converters (MMMC) operate at low frequency, sub-module (SM) capacitors voltage mainly contains doubling-output frequency component inversely proportion to output frequency, especially when MMMC operate at zero frequency, the voltage ripple of SM capacitor can be infinite in theory.

Modular multilevel matrix converter for low frequency AC transmission

2013 IEEE 10th International Conference on Power Electronics and Drive Systems (PEDS), 2013
The modular multilevel matrix converter (MMMxC) applied to a low frequency ac (LFAC) transmission system is investigated. The LFAC (1 Hz ~ 20 Hz) has some advantages compared to conventional ac and dc transmission systems, such as the increase of current-carrying capacity of power cables due to reduction of capacitive charging current, and better fault

Operation of modular multilevel matrix converters with failed branches

IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
Modular Multilevel Converters have a large number of advantages at high voltage and power levels. Due to their modular structure, they offer easy scalability, high quality output waveforms, and superior availability, to name a few. This paper aims at further increasing the availability of the Modular Multilevel Matrix Converter.
