Die Erfindung betrifft einen Ladegleichrichter mit Längsregler, der abhängig von der Ausgangsgleichspannung geregelt ist, und dessen Eingangstransformator mit mehreren Anzapfungen zur Erzeugung von mindestens zwei wählbaren Eingar.gsspannungen für den Längsregler versehen ist.The invention relates to a charging rectifier with a series regulator that is dependent on the DC output voltage is regulated, and its input transformer with several taps for the generation of at least two selectable input voltages are provided for the series regulator.
Aus der DE-OS 20 09 695 ist ein Ladegerät mit Längsregler bekannt, bei dem für verschiedene Batteriespannungen der Transformator mit mehreren Anzapfungen versehen ist um den Längsregler mit verschiedenen Spannungen zu versorgen.From DE-OS 20 09 695 a charger with series regulator is known in which for different battery voltages the transformer is provided with several taps around the series regulator with different To supply tension.
Aus der DE-AS 26 09 435 ist ferner die Verwendung von gesteuerten Ventilen 19, 20 zur Zuschaltung von weiteren Transformator-Teilwicklungen unier Verwendung eines Reglers bekannt.From DE-AS 26 09 435 is also the use of controlled valves 19, 20 for switching on further transformer part windings for use of a controller known.
Ladegleichrichter mit Längsregler haben den Vorteil einer oberwellenarmen Ausgangsgleichspannung bei einem Wirkungsgrad, der sehr stark vom Eingangsspannungsbereich abhängig ist.Charging rectifiers with series regulator have the advantage of a low-harmonic output DC voltage an efficiency that is very dependent on the input voltage range.
Deshalb können derartige Längsregler nur innerhalb eines bestimmten Regelbereiches die Ausgangsspannung mit einem guten Wirkungsgrad regeln.This is why series regulators of this type can only control the output voltage within a certain control range regulate with good efficiency.
Aufgabe der vorliegenden Erfindung ist es, einen Ladegleichrichter zu schaffen, der unter Beibehaltung der für den Längsregler günstigen oberwellenarmen Ausgangsspannung die Ausregelung über einen größeren Regelbereich hinweg gestattet.The object of the present invention is to provide a charging rectifier that while maintaining the low-harmonic output voltage, which is favorable for the series regulator, is compensated by a larger one Control range permitted.
Zur Lösung dieser Aufgabe wird der Ladegleichrichter gemäß der Erfindung derart ausgebildet, daß die Sekundärwicklung des Eingangstransformators des Gleichrichters aus einer Hauptwicklung und mindestens zwei weiteren Teilwicklungen besteht, die bedarfsweise über gesteuerte Ventile im Sinne einer Erhöhung der ungeregelten Gleichspannung abhängig von vorgegebeiü nen Grenzwerten der Gleichspannung über dem Längsregelkreis angeschaltet sind.To solve this problem, the charging rectifier according to the invention is designed such that the Secondary winding of the input transformer of the rectifier from a main winding and at least there are two further partial windings, which if necessary have controlled valves in the sense of increasing the unregulated DC voltage depending on preset NEN limit values of the DC voltage are switched on via the series control loop.
Als gesteuerte Ventile können dabei vorteilhaft Thyristoren verwendet werden.Thyristors can advantageously be used as controlled valves.
Durch diese Maßnahmen erhält man einen Ladegleichrichter, bei dem die Vorteile des ungeregelten Gleichrichters und des Transistorlängsreglers voll erhalten bleiben. Der Wirkungsgrad kann sogar gegenüber einem normalen Längsregler um 10% gesteigert werden.These measures result in a charging rectifier in which the advantages of the unregulated Rectifier and the transistor linear regulator are fully preserved. The efficiency can even can be increased by 10% compared to a normal series regulator.
Zur Erzeugung der Schaltkriterien werden Grenzwertdetektoren die parallel zum Längsregelkreis liegen, verwendet.To generate the switching criteria, limit value detectors are used that are parallel to the longitudinal control loop, used.
Anhand des Ausführungsbeispiels nach der Figur wird die Erfindung näher erläutert.The invention is explained in more detail using the exemplary embodiment according to the FIGURE.
Die Netzspannung wird dem Eingangstransformator 1 zugeführt. Die Sekundärwicklung 2 weist dabei eine mittelangezapfte Hauptwicklung 3 und zwei weitere Teilwicklungen 4 auf. Der Gleichrichter mit den DiodenThe mains voltage is fed to the input transformer 1. The secondary winding 2 has a center tapped main winding 3 and two further partial windings 4. The rectifier with the diodes
6 der Siebdrossel 12 und dem Glättungskondensator 11 wird vor. der Hauptwicklung 3 gespeist. Die Teilwicklungen 4 sind mit dem Gleichrichterausgang über Thyristoren 5 verbunden, die bei Überschreiten einer eingestellten Spannungsschwelle über dem Längsregelkreis gesperrt sind. Dieser enthält einen Längstransistor 8 und einen Regelverstärker 9, der den Längstransistor 8 in Abhängigkeit von der Ausgangsspannung steuert, so daß am Ausgang eine geregelte Gleichspannung erhalten wird.6 of the filter choke 12 and the smoothing capacitor 11 is in front. the main winding 3 fed. The partial windings 4 are connected to the rectifier output via thyristors 5, which when a set voltage threshold above the longitudinal control loop are blocked. This contains a series transistor 8 and a control amplifier 9, which controls the series transistor 8 depending on the output voltage, so that a regulated DC voltage is obtained at the output.
Sinkt die Spannung über den Längstransistor 8 jedoch um einen vorgegebenen Betrag ab, so spricht die Thyristorsieuerung 7 mit Hilfe von Detektoren an und zündet die Thyristoren 5. Dadurch werden die beiden Zusatzwicklungen der Hauptwicklung aufgeschaltet und die Ausgangsspannung steigt damit um den der Teilwicklung 4 entsprechenden Spannungsbetrag an.If the voltage across the series transistor 8 drops by a predetermined amount, however, the speaks Thyristorsieuerung 7 with the help of detectors and ignites the thyristors 5. This causes the two Additional windings of the main winding are connected and the output voltage increases by that of the Part winding 4 corresponding voltage amount.
Bei steigender Spannung über dem Längstransistor 8 werden die Thyristoren 5 durch die ThyristorsteuerungWhen the voltage across the series transistor 8 rises, the thyristors 5 are controlled by the thyristor control
7 nicht mehr angesteuert, die Zusatzwicklung 4 am Eingangstransformator wird wieder unwi.-ksam.7 no longer activated, the additional winding 4 on the input transformer becomes invalid again.
Mit dieser Regelung wird das Prinzip des Längsreglers mit dem des Stufenreglers verknüpft, wodurch ein besonders günstiger Wirkungsgrad erhalten wird.With this regulation, the principle of the series regulator is linked with that of the step regulator, whereby a particularly favorable efficiency is obtained.
