van der Sande, Robin (author), Deshmukh, R.S. (author), Shekhar, A. (author), Bauer, P. (author)When operating a modular multilevel converter (MMC), a margin appears between the arm voltage and sum capacitor voltage corresponding to the power dependent ripple. This margin can be used to enhance the DC link voltage and increase the transfer capacity of an MMC-based distribution link while keeping the submodule (SM) stresses fixed....conference paper 2023
