ABSTRACT:
A triggering method for a thyristor switch which has at least two thyristors wired in series and a thyristor wired in antiparallel to each of these thyristors. The thyristor switch is triggered or cut off as a function of a specifiable on-off signal. At least a single triggering of a thyristor to be switched-on takes place at the earliest if a positive anode-cathode voltage is applied to it which exceeds a specifiable switch-on voltage limiting value. The method comprises generating a trigger standby signal if the on-off signal is in the switch-on condition and, with a specifiable minimum number of thyristors to be triggered wired in series, their anode-cathode voltage is greater than the specifiable switch-on voltage limiting value. At least a single triggering of each thyristor to be switched on takes place by means of a short-duration trigger pulse only during the duration of the trigger standby signal.
