Abstract: A converter arrangement can include a first rectifier having an AC input and a DC output with two DC output poles, a capacitance (C) connected between the DC output poles of the first rectifier, a second rectifier having an AC input with two AC input poles and a DC output with two DC output poles, wherein the DC output of the second rectifier is connected between the DC output poles of the first rectifier. A magnetic amplifier includes at least one control winding (L2) and at least one AC winding (L11, L12), wherein the at least one control winding is connected between the DC output poles of the first rectifier, and wherein the at least one AC winding (L2) of the magnetic amplifier is connected in series with the AC input of the second rectifier.
