ZPUC9-MMC: An Increased Voltage Level Modular Multilevel Converter

2021 22nd IEEE International Conference on Industrial Technology (ICIT), 2021
In this paper a nine level Z-packed U-cell (ZPUC9) multilevel converter has been proposed as a submodule of modular multilevel converter (MMC) to increase the voltage level at the output waveform. Single DC source ZPUC9-MMC generates 17-level phase voltage and 33-Level line voltage waveform through single submodule per arm which increases the voltage ...

Parameters design for modular multilevel converter (MMC)

2013 Brazilian Power Electronics Conference, 2013
The modular multilevel converter is one of the most interesting transformerless multilevel converter topology intended for medium and high-voltage power conversion. Thus, as a new topology, a fewer design guidelines are presented in the literature, on the other hand there are many restrictions.

Decoupled αβ model of modular multilevel converter (MMC)

2017 IEEE Energy Conversion Congress and Exposition (ECCE), 2017
The modular multilevel converter (MMC), is widely adopted in high voltage applications because of its simplicity and modularity. However, the current and power flow is very complicated. As a result, methods proposed for capacitor reduction, which is required to stored line frequency related circulating energy, all went through complicated mathematical ...

Modular multilevel converter (MMC) based resonant high voltage multiplier

2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015
This paper addresses the limitation of current technologies in the interconnection between medium-voltage (MV) DC and high-voltage (HV) DC grids. One transformerless approach is proposed to achieve bidirectional high power transfer and high step up/down ratio, which can be configured to interface with different grids connection. The proposed technology

Design and Analysis Methodology for Modular Multilevel Converters (MMC)

IEEE Latin America Transactions, 2018
The design and analysis of the modular multilevel converter (MMC) are usually performed with simulation softwares in an interactive mode. Each parameter is individually set in order to analyze the effect on the converter output, which in turn, demands a lot of time of the user.

A Hybrid Modular Multilevel Converter (MMC) for MVDC Application

2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia), 2019
This paper presents a hybrid modular multilevel converter (MMC) applied in medium voltage dc (MVDC) system that is able to generate more voltage levels on the arms when the same or even less number of sub-modules are utilized. Each arm of the presented MMC is comprised of the upper part (made of series-connected half-bridge submodules (HBSMs)) and the ...

Power balancing in multi-converter systems composed of modular multilevel converters (MMCs)

2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe), 2016
Multi-converter systems composed of series or parallel connected modular multilevel converters (MMCs) require a means to manage power sharing between the MMCs by balancing the load during operation. Series connected MMCs require proper voltage balancing while parallel connected MMCs require proper current balancing.

A novel voltage balancing method of Modular Multilevel Converter (MMC)

2011 International Conference on Energy, Automation and Signal, 2011
The main problem in the new potential Modular Multilevel converter (MMC) topology for high and medium level is the voltage balancing of the capacitors of their sub modules. The novel balancing technique which is introduced in this paper based on sorting of the capacitor voltages. After sorting and detection of the arm current direction, neither require
