Capacitor selection for modular multilevel converter
2014 IEEE Energy Conversion Congress and Exposition (ECCE), 2014Submodule (SM) capacitor is a key component in a modular multilevel converter (MMC), the selection of which must consider the component’s specifications and the requirements of the targeted converter application. This paper focuses on the capacitor selection for MMCs in applications including high-voltage direct current (HVDC) transmission and static ...

A Prototype of Modular Multilevel Converters
IEEE Transactions on Power Electronics, 2014This paper introduces a modular multilevel converter (MMC) based prototype for investigating the control of large-scale MMCs. The prototype contains 264 submodules (SMs) totally, which are designed in such a way that they can be rearranged between the half-bridge model and full-bridge model conveniently.

Global Asymptotic Stability of Modular Multilevel Converters
IEEE Transactions on Industrial Electronics, 2014Modular multilevel converters require that the controller is designed so that the submodule capacitor voltages are equalized and stable, independent of the loading conditions. Assuming that the individual capacitor-voltage sharing is managed effectively, an open-loop strategy has been designed to ensure that the total amount of energy stored inside the

A Novel Modular Expandable Multilevel Converter
International Journal of Circuit Theory and ApplicationsABSTRACTMultilevel 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.

Power Decoupling Control for Modular Multilevel Converter
IEEE Transactions on Power Electronics, 2018The existing power decoupling control method of modular multilevel converter (MMC) was developed from that of conventional two-level voltage source converters. Therefore, it cannot fully realize power decoupling due to neglecting the coupling effects from submodule capacitor voltage, dc current, circulating current as well as control strategies of ...

A novel nine-arm modular multilevel converter
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014In many applications, such as motor drives and integrating distribute power sources into a grid, there are two or more ac sources or loads. The conventional solution is to use separate modular multilevel converters, which increases cost and volume of system.

Performance of the modular multilevel converter with redundant submodules
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015The 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 ...
