Abstract

1. Rectifier which has at its input an alternating-current connection and at its output a direct-current connection, a) having at least one load thyristor for each phase of the alternating current, b) having at least one turn-off device for the load thyristors, c) having an over-voltage limiter (40, 41) in parallel with the direct-voltage output of the rectifier, d) a separate turn-off device (34, 36, 38; 35, 37, 39) being provided for each phase of the alternating current and e) being connected in parallel with a load thyristor (30, 31) to be turned off, characterized in f) that each of the turn-off devices has its own turn-off capacitor (34, 35) and a reverse-conducting gate turn-off thyristor (38, 39) which is connected in parallel with the capacitor and which is polarized in the same direction as the associated load thyristor to be turned off.
