Abstract

The thyristor switch must typically deal with an inductive and resistive load (5). The switch is closed by an electronic timing, or firing circuit (14) driving the base of the main thyristor (3). To open the switch a further thyristor (8) is connected across the switching thyristor, and a number of other components including a specially constructed inductance (18) are used. This second thyristor is again driven by the electronic timing circuit, and depending on the various conditions, the first thyristor is switched off by means of an inductively induced reverse voltage produced for a time dependent on these conditions.
