ZPUC9-MMC: An Increased Voltage Level Modular Multilevel Converter
2021 22nd IEEE International Conference on Industrial Technology (ICIT), 2021In 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 ...

Decoupled αβ model of modular multilevel converter (MMC)
2017 IEEE Energy Conversion Congress and Exposition (ECCE), 2017The 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 ...

A Hybrid Modular Multilevel Converter (MMC) for MVDC Application
2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia), 2019This 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 ...

Optimal Control of Modular MultiLevel Converters (MMCs) for Minimum Storage Requirement
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018With the push towards Medium Voltage DC (MVDC) based electrical distribution systems, the power converter(s) between Medium Voltage AC generators and common MVDC buses must handle more power than any other electrical power conversion component in the distribution system. The Modular Multi-Level Converter (MMC) is a compelling topology for this function

IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013
Based on pin-pointing the theoretical origin, the second harmonic current in MMC is eliminated at the source and, with it, the low frequency harmonics which proliferate from it. The implications of the elimination to MMC HVDC and MMC STATCOM are discussed.
