Absorption circuit arrangement for a traction converter of a rail vehicle

An absorption circuit configuration for a traction converter of a rail vehicle, the traction converter having at least one supply-side first power converter, at least one load-side second power converter, a DC link circuit connecting the at least one supply-side first power converter and the at least one load-side second power converter with a first and a second voltage potential and at least one link circuit capacitance disposed in the DC link circuit, the absorption circuit configuration disposed in the DC link circuit and connected in parallel with the at least one link circuit capacitance, the absorption circuit comprising:

• at least one switching configuration having at least one switching unit and at least one inductance, wherein each said at least one switching unit has two terminals, at least two controllable power semiconductor switches and at least one switching unit capacitance and is configured, dependent upon switching settings of said controllable power semiconductor switches, to provide at least two different voltages at said two terminals, and wherein said at least one inductance is connected in series with said at least one switching unit;
• at least one capacitive energy store, wherein said at least one capacitive energy store is connected in series with said at least one switching configuration;
• and
• a controller, wherein said controller is configured to control at least said controllable power semiconductor switches of said at least one switching unit.
