Abstract: A modular converter is disclosed which includes plural converter cells connected in series on a first side, and connected on a second side, wherein each converter cell includes an AC-to-DC converter connected to the first side and a DC-to-DC converter connected to the second side. Exemplary embodiments estimate power transferred by the modular converter; compare the transferred power with a threshold value; when the transferred power exceeds the threshold value, operate in a normal load operation mode; when the transferred power is below the threshold value, operate in a low load operation mode with reduced switching losses.
