Submodule and electrical arrangement having submodules

A configuration, comprising:

• a plurality of submodules which are electrically connected in series to form a submodule series circuit and respectively each of said submodules containing:
• a first outer electrical terminal for an electrical configuration;
• a second outer electrical terminal for the electrical configuration;
• at least one bypass switching device electrically connected between said first and second outer electrical terminals and in an on-state causes an electrical short-circuit between said first and second outer electrical terminals, said bypass switching device containing:
• a first thyristor having an anode terminal, a cathode terminal and a trigger terminal and is connected by said anode terminal to said first outer electrical terminal and by said cathode terminal to said second outer electrical terminal;
• a second thyristor having an anode terminal connected to said second outer electrical terminal, a cathode terminal connected to said first outer electrical terminal and a trigger terminal;
• a first triggering device, connected to said trigger terminal of said first thyristor, for triggering said first thyristor, wherein said first triggering device is electrically connected between said trigger terminal of said first thyristor and said second outer electrical terminal;
• a first switch, which in an on-state connects said anode terminal of said first thyristor to said trigger terminal of said first thyristor, said first switch in the on-state connects said anode terminal of said first thyristor, and therefore said first outer electrical terminal, to said trigger terminal of said first thyristor;
• a second switch, said second switch in an on-state connects said anode terminal of said second thyristor, and therefore said second outer electrical terminal, to said trigger terminal of said second thyristor;
• a second triggering device electrically connected between said trigger terminal of said second thyristor and said first outer electrical terminal;
• at least one control device, which in a presence of a bypass activation signal activates said first and second triggering devices with a triggering signal and closes said first and second switches;
• and
• said at least one control device is configured in such a way that said control device applies triggering signals for triggering said first and second thyristors to said trigger terminal at least until said first and second switches have reached the on-state;
• and
• an electrically inner-lying submodule of said submodule series circuit being connected by said first outer electrical terminal to said second outer electrical terminal of said submodule, lying at a higher potential, of said submodule series circuit and by said second outer electrical terminal to said first outer electrical terminal of said submodule, lying at a lower potential, of said submodule series circuit.
