An Isolated Modular Multilevel Converter (I-M2C) Topology Based on High-Frequency Link (HFL) Concept
IEEE transactions on power electronics, 2020This paper introduces the high-frequency link concept into the modular multilevel converter (MMC) topology, which can totally reduce the individual dc-link capacitors at the high-voltage side. The proposed converter, called isolated MMC, has basic triple

A Modular Multilevel Converter With Self-Voltage Balancing Part I: Mathematical Proof
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020The modular feature of the modular multilevel converter (MMC) distinguishes itself from other topologies for medium-/high-voltage applications. However, as the count of submodules increases, the control complexity of voltage balancing for each submodule ...

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.
