  Steueranordnung zum Zünden von wechselstromgespeisten bilateral schaltenden Thyristorsystemen durch ein bilateral schaltendes
Leitthyristorsystem 
Steht man vor dem Problem, mehrere Verbraucher, z. B. Lampen, mittels mehrerer bilateral schaltender Thyristorsysteme (das sind steuerbare Halbleiterelemente, die in ihrem Verhalten zwei antiparallelen Thyristoren mit einer einzigen gemeinsamen Steuerelektrode entsprechen) synchron im Phasenanschnitt von einer Phase einer Wechselspannungsquelle zu betreiben, ist eine Gittersteuerschaltung erforderlich, die ein praktisch gleichzeitiges Zünden aller bilateral schaltenden Thyristorsysteme sicherstellt. 



   Die Erfindung löst diese Aufgabe mit wenig Aufwand in sehr vorteilhafter Weise. Ihr Gegenstand ist eine Steueranordnung zum Zünden von wechselstromgespeisten bilateral schaltenden Thyristorsystemen in Abhängigkeit von einem bilateral schaltenden Leitthyristorsystem, mit dem Kennzeichen, dass an die Schaltstrecke des Leitthyristorsystems der Eingang eines Differenziergliedes angeschlossen ist, dessen Ausgang mit der Steuerstrecke des zu zündenden Thyristorsystems verbunden ist. Der Gitterimpuls für das letztere wird also durch Differentiation der Anodenspannung des Leitthyristorsystems erzeugt. 



   Die Zeichnungen zeigen Ausführungsbeispiele. Die Lastwiderstände sind mit-P-bezeichnet. 



  Nach Fig. l wird das bilateral schaltende   Thyristorsystem --TRl-- fremd   gesteuert, das bilateral 
 EMI1.1 
 



   Sind mehr als zwei bzw. eine Vielzahl von bilateral schaltenden Thyristorsystemen vorhanden, so können im Sinne der Erfindung von einem Leitthyristorsystem alle übrigen durch Differentiation der Anodenspannung des ersteren gesteuert werden. Eine andere Möglichkeit besteht darin, dass sämtliche bilateral schaltende Thyristorsysteme eine Kette bilden, bei der das jeweils folgende von dem ihm vorhergehenden gezündet wird. 



   Ein Vorteil der erfindungsgemässen Schaltung besteht darin, dass man bei Verwendung einer Mehrzahl von bilateral schaltenden Thyristorsystemen nur einen Zündimpulsgeber geringer Leistung benötigt.

  Control arrangement for triggering alternating current supplied bilaterally switching thyristor systems by a bilaterally switching
Conductive thyristor system
If you are faced with the problem of having several consumers, e.g. B. lamps, by means of several bilaterally switching thyristor systems (these are controllable semiconductor elements that correspond in their behavior to two anti-parallel thyristors with a single common control electrode) synchronously in phase control of one phase of an AC voltage source, a grid control circuit is required, which a practically simultaneous ignition of all bilaterally switching thyristor systems.



   The invention solves this problem in a very advantageous manner with little effort. Its subject matter is a control arrangement for triggering alternating current fed bilaterally switching thyristor systems as a function of a bilaterally switching conductive thyristor system, with the characteristic that the input of a differentiating element is connected to the switching path of the conductive thyristor system, the output of which is connected to the control path of the thyristor system to be ignited. The grid pulse for the latter is thus generated by differentiating the anode voltage of the conductive thyristor system.



   The drawings show exemplary embodiments. The load resistances are labeled -P-.



  According to Fig. 1, the bilaterally switching thyristor system --TRl-- is controlled externally, the bilateral
 EMI1.1
 



   If more than two or a large number of bilaterally switching thyristor systems are present, then, within the meaning of the invention, all the others can be controlled by a lead thyristor system by differentiating the anode voltage of the former. Another possibility is that all bilaterally switching thyristor systems form a chain in which the next one is triggered by the one preceding it.



   One advantage of the circuit according to the invention is that, when using a plurality of bilaterally switching thyristor systems, only one low-power ignition pulse generator is required.
