APPARATUS FOR FIRING SERIES-CONNECTED THYRISTORS Abstract of the Disclosure An apparatus for simultaneously fixing a plurality of series-connected thyristors having a control pulse trans- former for each thyristor. Each transformer has first and second primary windings, with the first windings being connected in series with each other, and the series combination being connected through an auxiliary thyristor to a capacitor which is charged from a DC voltage source. The second primary windings are also connected in series with each other with the series combination being connected to a DC source through a tran- sistor switch means. In half of the transformers the two primary windings have the same polarities, while in the other half they have opposite polarities. To fire the thyristors, the auxiliary thyristor is caused to be fired causing the transformers to provide a steep pulse with a high amplitude to the thyristors, At the end of the initial pulse, the transistor switch means is activated and the transformers thereafter deliver a continuous control current having a lower amplitude to the thyristors.
