2020/04/26 - Congratulations to PhD student Yuan Li on acceptance of the paper "The Modular Multilevel DC Converter with Inherent Minimization of Arm Current Stresses" in the IEEE Transactions on Power Electronics! The modular multilevel dc converter (M2DC) is well suited for MVDC-MVDC or HVDC-HVDC conversion, however, internal ac current stresses go up as the dc step ratio increases, ultimately rendering it impractical for applications such as HVDC-MVDC conversion. This work introduces a modified M2DC structure that overcomes this fundamental limitation by using a center-tapped transformer to minimize ac current stresses at any dc step ratio. Potential applications include HVDC line power tapping, HVDC-MVDC grids interconnects, and connection of offshore wind MVDC collector networks to HVDC.
