Abstract (en)
The trigger circuit(23) has an input(27) connected to the common point of a resistance(4) and to two diodes(3,6). Thyristor conduction is triggered when the first terminal(1) of the a.c. supply is near its most negative potential with respect to the second(2) a.c. supply terminal. The trigger circuit(23) of the thyristor(9) has a transistor(28) whose collector is connected to the trigger of the thyristor(9). The transistors emitter is connected to the midpoint of a capacitor(14) and resistor(13) and the base is connected to the input(27). The transistor(28) conducts when the first terminal is near to its most negative potential with respect to the terminal(2)..
Abstract (fr)
Le circuit de déclenchement 23 comporte une entrée 27 reliée au point commun à la résistance 4 et aux diodes 3 et 6, et une entrée 25 reliée à la borne d'entrée 1. La mise en conduction du thyristor est déclenchée lorsque la première borne 1 est au voisinage de son potentiel le plus négatif par rapport à celui de la deuxième borne 2. <IMAGE>
