Description
Die Hauptpa.tentanmeld.ung betrifft einen kontaktlosen Zweipunktregler mit einer Kaskadenendstufe mit Schalttransistoren in Kollektorverbundbetrieb, deren Sperrspannungen durch eine Spannungsteilerschaltung erzeugt werden. Unter Kollektorverbundbetrieb wird verstanden, daß der Lastwiderstand für sämtliche Transistoren als Kollektorwiderstand wirkt. Dadurch erzielt man den wesentlichen Vorteil, daß der Kollektorstrom aller Transistoren der Kaskade für den Lastwiderstand zur Verfügung steht.The main patent application concerns a contactless one Two-point controller with a cascade output stage with switching transistors in collective collector operation, their Reverse voltages are generated by a voltage divider circuit. Under collective collector operation is understood that the load resistance acts as a collector resistance for all transistors. Through this one achieves the essential advantage that the collector current of all the transistors of the cascade for the Load resistance is available.
Die letzte Transistorstufe, die den größten Kollektorstrom führt, muß im geöffneten Zustand eine Spannung übernehmen, die als Kollektorspannung für die Vorstufen ausreicht. Dies bedingt eine relativ hohe Verlustleistung des Endtransistors, die sich aus dem Produkt dieser Spannung und dem Kollektor strom ergibt.The last transistor stage, which carries the largest collector current, has to be one when it is open Take over voltage that is sufficient as collector voltage for the preliminary stages. This requires a relatively high Power dissipation of the final transistor resulting from the The product of this voltage and the collector current is the result.
Zur Vermeidung dieses Nachteiles wird gemäß der Erfindung im Kollektorkreis wenigstens der letzten Stufe ein Widerstand angeordnet, der bei geöffnetem Transistor die Kollektorspannung für die Vorstufen erzeugt. Der Endtransistor wird daher von der Lieferung der Kollektorspannung für die Vorstufen entlastet und kann so weit geöffnet werden, wie es auf Grund seiner Kennlinie überhaupt möglich ist. Die Verlustleistung des Transistors kann dabei um 50% und mehr verringert werden, oder, mit anderen Worten, die Schaltleistung kann um einen entsprechenden Betrag erhöht werden.To avoid this disadvantage, according to the invention, at least the last one in the collector circuit Stage a resistor is arranged which, when the transistor is open, the collector voltage for the preliminary stages generated. The output transistor is therefore relieved of the supply of the collector voltage for the pre-stages and can be opened as far as it is possible due to its characteristic curve. the The power loss of the transistor can be reduced by 50% and more, or, in other words, the switching capacity can be increased by a corresponding amount.
Zur näheren Erläuterung der Erfindung wird nachstehend ein Ausführungsbeispiel beschrieben, das in der Zeichnung schematisch dargestellt ist. Es wurden dabei die Bezugszeichen.aus der Zeichnung derHauptpatentanmeldung übernommen, soweit übereinstimmende Schaltungselemente vorliegen.To explain the invention in more detail, an embodiment is described below, which is shown in the drawing is shown schematically. The reference numbers were used from the drawing of the main patent application accepted, provided that matching circuit elements are present.
Wie die Figur zeigt, wird die Schaltung nach der Hauptpatentanmeldung gemäß der Erfindung durch einen Widerstand 11 im Kollektorkreis des Endtransistors 4 ergänzt. Dieser Widerstand wird so groß bemessen, daß der volle Durchlaßstrom des Transistors 4 an ihm einen Spannungsabfall erzeugt, der als Kollektorspannung für die Vorstufen ausreicht.As the figure shows, the circuit according to the main patent application according to the invention is carried out by a resistor 11 in the collector circuit of the final transistor 4 added. This resistance is dimensioned so large that the full forward current of the transistor 4 generates a voltage drop across it, which is sufficient as collector voltage for the pre-stages.
Es hat sich ergeben, daß auch bei unterschiedlichen Kenndaten der einzelnen Transistoren infolge der Exemplarstreuung eine individuelle Abstimmung des Widerstandes 11 nicht erforderlich ist. Auch können größere Toleranzen für den Widerstands wert zugelassen werden.It has been found that even with different characteristics of the individual transistors due to the Individual variation of the resistor 11 is not required. Also can larger tolerances for the resistance value are permitted.
Es ist möglich, nicht nur in den Kollektorkreis des Endtransistors, sondern auch in den einer VorstufeIt is possible not only in the collector circuit of the output transistor, but also in that of a pre-stage

einen zusätzlichen Widerstand einzuschalten. Diese Maßnahme kann bei Kaskaden mit vielen Stufen vorteilhaft sein.to switch on an additional resistor. This measure can be advantageous for cascades with many stages be.
Da nunmehr die letzte Stufe der Kaskade nicht mehr die Kollektorspannung der Vorstufen liefern muß, kann beim Erfindungsgegenstand mit besonderem Vorteil auch eine Parallelschaltung mehrerer Transistoren in der letzten Stufe vorgenommen werden. Dadurch erst wird eine weitere wesentliche Erhöhung der Schaltleistung einer solchen Kaskade möglich.Since now the last stage of the cascade no longer supplies the collector voltage of the preliminary stages must, with the subject matter of the invention, a parallel connection of several Transistors are made in the last stage. Only then will there be a further substantial increase the switching capacity of such a cascade is possible.
