  • Patent number: 6377107
    Abstract: A circuit arrangement having at least one electric main switch (T1) with a reference electrode (E), a control electrode (B), and a work electrode (C). A recovery diode (D1; D2) is connected antiparallel to the main flow direction of each main switch (T1). In order to speed up the switch-off process and in particular to reduce the attendant power loss, each main switch (T1) is assigned an electric auxiliary switch (T11; T22), whose work electrode is connected to the control electrode (B) of the associated main switch (T1) and whose reference electrode is connected to the reference electrode (E) of the associated main switch (T1). The capacitor (C11) is disposed between the control electrode of the auxiliary switch (T11; T22) and the work electrode (C) of the associated main switch (T1).
