  "textContent": "The present disclosure relates to a STATCOM arrangement () comprising an MMC () and a transformer arrangement () arranged to be an interface between the MMC () and an AC grid. The MMC () is connected in a wye topology with a plurality of converter arms, one for each phase of the AC grid, each arm comprising a plurality of chain-linked converter cells. The transformer arrangement () is arranged to interface each of the arms of the MMC () with a respective phase of the grid, and arranged to for each of the converter arms produce leakage reactance resulting in reactance in series with the arm which obviates the need for a phase reactor connected in series with said arm.",
