A modular converter (10) comprises a plurality of converter cells (36), which are connected in series on a first side and are connected on a second side, wherein each converter cell (36) comprises an AC-to-DC converter (40) connected to the first side and a DC-to-DC converter (42) connected to the second side. A method for controlling the modular converter (10) comprises the steps of: estimating the power transferred by the modular converter (10); comparing the transferred power with a threshold value; when the transferred power is bigger than the threshold value, operating the modular converter in a normal load operation mode (1 16, 122, 128); when the transferred power is smaller than the threshold value, operating the modular converter in a low load operation mode (1 14, 120, 126), in which the converter cells (36) are operated, such that switching losses are reduced with respect to the normal load operation mode.
