An absorption circuit arrangement is for a traction converter of a rail vehicle. The traction converter has a first power converter, a second power converter, a DC link circuit connecting the first power converter and the second power converter with a first and a second voltage potential and a link circuit capacitance arranged in the DC link circuit. The absorption circuit arrangement is arranged in the DC link circuit and is connected in parallel with the link circuit capacitance and contains a switching arrangement having a switching unit and an inductance. Each switching unit contains two terminals, two controllable power semiconductor switches and a switching unit capacitance and is configured, dependent upon switching settings of the power semiconductor switches, to provide at least two different voltages at the terminals.
