Switch arrangement for a converter

A converter system (2) with

• at least one converter (3) comprising at least one switch arrangement (1) for controlling power conversion by the at least one converter (3);
• wherein the switch arrangement (1) comprises:
• a first series connection (SC1) of at least two switches (SL1, SR1) between two terminals (T1, T2) of the switch arrangement (1), wherein the two switches (SL1, SR1) are semiconductor switches;
• a second series connection (SC2) of a first capacitor (C1) and a first diode circuit (D1) electrically connected in parallel to a first part (P1) of the first series connection (SC1) between a first terminal (T1) of the two terminals (T1, T2) and a node (Nc) between the two switches (SL1, SR1), wherein the first diode circuit (D1) comprises at least one diode (D11);
• and
• a third series connection (SC3) of a second capacitor (C2) and a second diode circuit (D2) electrically connected in parallel to a second part (P2) of the first series connection (SC1) between a second terminal (T2) of the two terminals (T1, T2) and the node (Nc) between the two switches (SL1, SR1), wherein the second diode circuit (D2) comprises at least one diode (D21).
