A STATCOM arrangement includes 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 including 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.
