Die Erfindung betrifft einen geregelten Gleichspannungsumsetzer, bei dem ein im Strompfad liegender Schalttransistor durch einen durch die Regelgröße beeinflußbaren Taktgeber periodisch geöffnet und gesperrt wird.The invention relates to a regulated DC voltage converter in which a switching transistor located in the current path is periodically opened and blocked by a clock that can be influenced by the controlled variable.
Es ist bereits eine derartige Anordnung bekannt, bei der als Taktgeber ein astabiler Multivibrator dient. Dem aus zwei Transistoren, einem Kondensator und mehreren Widerständen bestehenden Multivibrator wird als Regelgröße eine von der Ausgangsspannung des Umsetzers abgeleitete, der Differenz aus Ist- und Sollspannung proportionale Spannung an den Basen seiner beiden Transistoren zugeführt, wodurch die Dauer der einen Halbwelle der MuItivibratorausgangsspannung veränderbar ist. Über einen an den· Kollektoren der beiden Transistoren angeschlossenen Übertrager wird ein Hilfstransistor gesteuert, der mit dem im Strompfad liegenden Schalttransistor zu einer bistabilen. Kippänordnung zusammengeschaltet ist.Such an arrangement is already known in which an astable multivibrator is used as the clock generator. The one out of two A multivibrator consisting of transistors, a capacitor and several resistors is used as a control variable from the output voltage voltage at the bases derived from the converter and proportional to the difference between the actual and nominal voltage of its two transistors, whereby the duration of one half-wave of the multivibrator output voltage can be changed is. Via one connected to the collectors of the two transistors Transformer, an auxiliary transistor is controlled, which, together with the switching transistor in the current path, becomes a bistable.

Die Multivibratoren der bekannten Anordnungen haben den Fachteil, daß sie nur einen verhältnismäßig kleinen Regelbereich zulassen, wenn zu den Eingangs spannung s Schwankungen gleichzeitig LastSchwankungen dazukommen. Die in den Kultivibratoren verwendeten RC-Glieder können nämlich nicht beliebig groß gemacht werden./Der Größe der Kapazität setzen oft die räumlichen Ausmaße und die von der Alterung abhängigen KapazltätsSchwankungen eine Grenze. Andererseits muß der Widerstand des Zeitgliedes hinreichend klein sein, um über ihn noch den Transistor durchsteuern zu können. Technisch möglich ist daher mit den bekannten multivibratorgesteuerten Anordnungen nur ein Verhältnis der Durchsehaltzeit zur Periodenzeit von etwa 1v} 10. Ein größeres Verhältnis.ist auch-für die Begrenzung der Kurzschlußleistung sehr wichtig. .-__ _,The multivibrators of the known arrangements have the technical part that they only allow a relatively small control range when the input voltage s fluctuations at the same time load fluctuations are added. The RC elements used in the cultivibrators cannot be made arbitrarily large. The size of the capacity is often limited by the spatial dimensions and the aging-dependent capacity fluctuations. On the other hand, the resistance of the timing element must be sufficiently small to still be able to control the transistor through it. Technically possible with the known multivibrator-controlled arrangements is therefore only a ratio of the hold-through time to the period time of about 1v } 10. A larger ratio is also very important for limiting the short-circuit power. .-__ _,

According to a further embodiment of the invention may therefore also of the said arrangement, a plurality, for "B.} may be provided two, one of which is a function of the output current and the other as a function of the off transition voltage of the converter control a.
An Hand eines Ausführungsbeispieles wird die Erfindung näher erläutert. In der Zeichnung gemäß Pig. 1 ist die Anordnung für einen Gleichspannungsumsetzer wiedergegeben, der die beispielsweise aus dem Wechselstromnetz bezogene und gleichgerichtete oder von einer Batterie stammende Spannung Ue auf die erforderliche Betriebsspannung Ua herabsetzt. Im Strompfad des Umsetzers liegt die Kollektor-Einitter-Sfcrecke eines Schalttransistors TS, der durch einen im wesentlichen aus einem Transistor TG und einem Übertrager U bestehenden, induktiv rückgekoppelten Impulsgenerator periodisch geöffnet und gesperrt wird. Zu diesem Zweck ist die Steuerstrecke des Schalttransistors TS mit einer Wicklung 1 des Übertragers ti verbunden.. Eine andere Wicklung 4- ist über einen Gleichrichter D1 an die Kollektor-Emitter-Strecke eines Transistors TCT,' eine weitere Wicklung 5 über einen Gleichrichter D2 an die Kollektor-Emitter-Strecke eines Transistors TU angeschlossen. Zwischen Basis- und Kollektor dieser Transistoren liegt jeweils ein Widerstand E2 bzw. S3. Beide Transistoren TJ, TU werden über je ein einstellbares Brückenglied gesteuert. Babel wird die Steuerspanauiig für den Transistor TJ durch den vom Iiaststrom abhängigen Spannungsabfall an einem im Ijaststromkrels angeordneten Widerstand RI bestimmt, während die Steuerspamiung für denThe invention is explained in more detail using an exemplary embodiment. In the drawing according to Pig. 1 shows the arrangement for a DC voltage converter, which reduces the voltage Ue, drawn for example from the AC network and rectified or derived from a battery, to the required operating voltage Ua. In the current path of the converter is the collector-one-emitter circuit of a switching transistor TS, which is periodically opened and blocked by an inductively fed back pulse generator consisting essentially of a transistor TG and a transformer U. For this purpose, the control path of the switching transistor TS is connected to a winding 1 of the transformer ti. Another winding 4- is connected to the collector-emitter path of a transistor TCT via a rectifier D1, another winding 5 via a rectifier D2 the collector-emitter path of a transistor TU connected. A resistor E2 or S3 is located between the base and collector of these transistors. Both transistors TJ, TU are each controlled via an adjustable bridge element. Babel, the control voltage for the transistor TJ is determined by the voltage drop, which is dependent on the load current, at a resistor RI arranged in the load current circuit, while the control voltage for the

Transistor TU von der Ausgangsspannung Ua des Umsetzers abgeleitet wird. Zur Glättung der Betriebsspannung ist außerdem dem im Strompfad liegenden Schalttransistor TS eine aus dem Gleichrichter G, der Drossel Dr und dem Kondensator 0 bestehende bekannte Siebkette nachgeschaltet.Transistor TU derived from the output voltage Ua of the converter will. To smooth the operating voltage, the switching transistor TS in the current path is also off the rectifier G, the reactor Dr and the capacitor 0 existing known sieve chain connected downstream.
Aus der Fig. 2 geht die Kurvenform der dem Schalttransistor TS zugeführten Steuerspannung US hervor. Während der konstanten Durchsehaltzeit te ist die Steuerspannung Us rechteckförmig , und springt an deren Ende auf einen hohen Wert entgegengesetzter Polarität, wobei der Schalttransistor TS gesperrt wird. Die Steuerspannung Us sinkt annähernd nach einer e-Funktion ab, worauf der Impulsgenerator den nächsten Durchschaltimpuls erzeugt. Die Form der Steuerspannung Us rührt von der unterschiedlichen Belastung des Übertragers Ü her. Während der Durchschaltezeit te ist die Belastung durch den niederohmigen Basis-Emitter-Widerstand des Transistors TS gegeben; · die Gleichrichter DI, D2 sind in dieser Zeit gesperrt. Während der Sperrzeit T-te sind diese Gleichrichter jedoch durchlässig und liegen mit dem Transistor TJ bzw. TU in Reihe an der Spannung der Wicklung 4 bzw. 5. Die Kollektor-Emitter-Widerstände der Transistoren TJ, TU bilden damit während der Sperrzeit die Belastung für den Übertrager Ü. Zur Begrenzung der an den Wicklungen 4, 5 auftretenden Spannungsspitzen dienen die Widerstände R2, R3, denen zur wirksameren Begrenzung . auch noch jeweils ein nicht dargestellter KondensatOr parallel geschaltet sein kann. Die Sperrzeit T-te kann durch die den Steuerstrecken der Transistoren TJ, TU über die Brückenglieder zugeführten Steuerspannungen verändert werden. Wenn sich die Spannung Ue am Ümsetzereingang oder der Laststrom ändern, wird die Sperrzeit T-te verlängert oder verkürzt, so daß die Betriebsspannung TJa bis auf die statische Regelabweichung konstant bleibt. Bei Überschreiten des Nennstromes vergrößert sich die Sperrzeit. Demzufolge sinkt die Betriebs-From Fig. 2, the waveform of the switching transistor TS goes supplied control voltage US. During the constant Hold-through time te, the control voltage Us is rectangular, and jumps at the end to a high value of opposite polarity, the switching transistor TS being blocked will. The control voltage Us decreases approximately according to an exponential function from, whereupon the pulse generator sends the next switching pulse generated. The form of the control voltage Us comes from the different load of the transformer Ü her. During the switching time te, the load is due to the low-resistance Base-emitter resistance of the transistor TS given; · the rectifiers DI, D2 are blocked during this time. During the blocking time T-th, however, these rectifiers are permeable and are in series with the transistor TJ or TU at the voltage of winding 4 or 5. The collector-emitter resistors the transistors TJ, TU thus form the load for the transformer U during the blocking time. To the limit the voltage peaks occurring at the windings 4, 5 are used the resistors R2, R3, those for more effective limitation. a capacitor (not shown) can also be connected in parallel in each case. The blocking time T-te can be activated by the the control paths of the transistors TJ, TU via the bridge members supplied control voltages can be changed. if the voltage Ue at the transformer input or the load current change, the blocking time T-te is lengthened or shortened, so that the operating voltage TJa remains constant except for the static control deviation. When the rated current is exceeded the blocking time increases. As a result, the operating

Gleichrichtung und Siebung können dabei auch in anderer Weise erfolgen, wie auch grundsätzlich anstelle des Schalttransistors TS andere elektronische Schaltelemente, z.B. steuerbare Gleichrichter einsetzbar sind.It is possible to use the arrangement even if the operating voltage Ua is to be higher than the voltage Ue or a galvanic separation of these voltages is required »For this purpose, a transformer UT is required between points A1, B1 and A2, B2 (Fig ·. 3), whereby a rectifier G 1 has to be connected in series with its secondary winding. Rectification and filtering can also take place in a different manner, and in principle other electronic switching elements, for example controllable rectifiers, can also be used instead of the switching transistor TS.
