This takes place at time Z 1 in FIG. The quenching capacitor 5 then has the polarity shown in FIG. 5. The thyristor 2 thus has a voltage in the forward direction. At the moment that triggers each in series with the first thyristor in which the thyristor 3 is ignited, in order to drive the current path, viewed in the direction of current passage, 50 saturation choke 6 into saturation, a saturation choke is located here. a tension may occur. This voltage is because it is an embodiment of the invention that it is connected in series with that of the capacitor 5, the saturation chokes, viewed in current passage, as an overvoltage at the thyristor 2nd direction, the first thyristors are connected downstream. However, if the core of the saturation choke has the following, an embodiment is shown in FIG. 6 shown characteristic curve, it remains explained according to the example of the invention. the current flow in the thyristor 1 in saturation. The F i g. 1 shows the circuit diagram known per se. Triggering of the thyristor 3 occurs at the saturation of a pulse circuit arrangement. From a DC choke 6, that is, no voltage and thus no current source 10, an overvoltage at the thyristor 2 is generated via a thyristor 11.
