Abstract

The circuit provides two voltage levels for the unregulated dc supply without causing excessive ripple in the rectified voltage at the lower level. The secondary winding (2) of the rectifier transformer (1) has two sections. The main section (3) is connected to rectifier diodes (6), and provides the lower voltage supply to the series regulator (8,9) controlling the charging voltage of the battery. If the unregulated voltage falls below a set value, the higher voltage is switched in. The necessary measurement may be the voltage across the regulating transistor (8). The second stage comprises a thyristor rectifier (5) connected to the additional section (4) on the transformer secondary winding. The thyristor triggering can be controlled by the voltage detector (7). As the thyristors act only as switches, the output voltage ripple remains similar to that produced by the diode rectifier.

Description

Ladegleichrichter mit LängsreglerCharging rectifier with series regulator

Die Erfindung betrifft einen Ladegleichrichter mit Längsregler, der abhängig von der Ausgangsgleichspannung geregelt ist.The invention relates to a charging rectifier with series regulator, the is regulated depending on the DC output voltage.

Ladegleichrichter mit Längsregler haben den Vorteil einer oberwellenarmen Ausgangsgleichspannung bei einem Wirkungsgrad, der sehr stark vom Eingangsspannungsbereich abhängig ist.Charging rectifiers with series regulators have the advantage of low harmonics DC output voltage with an efficiency that is very much different from the input voltage range is dependent.

Deshalb können derartige Längsregler nur innerhalb eines bestimmten Regelbereiches die Ausgpgsspannung mit einem guten Wirkungsgrad regeln.This is why series regulators of this type can only be used within a certain range Control range regulate the output voltage with good efficiency.

Aufgabe der vorliegenden Erfindung ist es, einen Ladegleichrichter zu schaffen, der unter Beibehaltung der für Längsregler günstigen oberwellenarmen Ausgangsspannung die Ausregelung über einen größeren Regelbereich hinweg gestattet.The object of the present invention is to provide a charging rectifier to create the low harmonic waves, which are favorable for series regulators Output voltage allows regulation over a larger control range.

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, insbesondere Thyristoren im Sinne einer Erhöhung der ungeregelten Gleichspannung abhängig von vorgegebenen Grenzwerten der Gleichspannung über dem Längsregelkreis angeschaltet sind.To solve this problem, the charging rectifier according to the invention designed such that the secondary winding of the input transformer of the rectifier consists of a main winding and at least two further partial windings that if necessary via controlled valves, in particular thyristors in the sense of an increase of the unregulated DC voltage depending on specified limit values of the DC voltage are switched on via the longitudinal control loop.

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 take full advantage of the unregulated rectifier and the transistor linear regulator remain. The efficiency can even be compared to a normal series regulator can be increased by 10%.

Zur Erzeugung der Schaltkriterien werden Grenzwertdetektoren die parallel zum Längsregelkreis liegen, verwendet.To generate the switching criteria, limit value detectors are used in parallel to the longitudinal control loop are used.

Anhand des Ausführungsbeispiels nach der Figur wird die Erfindung näher erläutert.The invention is based on the exemplary embodiment according to the figure explained in more detail.

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 Dioden 6 der Siebdrossel 12 und dem Glättungskondensator 11 wird von 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 Längs- transistor 8 und einen Regelverstärker 9, der den Längstransistor 8 in Abhängigkeit von der Ausgangsspannung steuert, so daß am Ausgang eine geregelte Gleichspan nung erhalten wird.The 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 on. The rectifier with the diodes 6 of the filter choke 12 and the smoothing capacitor 11 is fed by the main winding 3. The partial windings 4 are connected to the rectifier output connected via thyristors 5, which when a set voltage threshold is exceeded are blocked via the longitudinal control loop. This contains a longitudinal transistor 8 and a control amplifier 9, the series transistor 8 depending on the Output voltage controls so that a regulated DC voltage is obtained at the output will.

Sinkt die Spannung über den Längstransistor 8 Jedoch um einen vorgegebenen Betrag ab, so spricht die Thyristorsteuerung 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.However, if the voltage across the series transistor 8 drops by a predetermined value From the amount, the thyristor control 7 responds with the aid of detectors and ignites the thyristors 5. This makes the two additional windings of the main winding switched on and the output voltage thus increases by that of the partial winding 4 Voltage amount.

Bei steigender Spannung über dem Längstransistor 8: werden die Thyristoren 5 durch die Thyristorsteuerung 7 nicht mehr angesteuert, die Zusatzwicklung 4 am Eingangstransformator wird wieder unwirksam.With increasing voltage across series transistor 8: the thyristors 5 is no longer controlled by the thyristor control 7, the additional winding 4 on Input transformer becomes ineffective again.

Mit dieser Regelung wird das Prinzip des Längsreglers mit dem des Stufenreglers verknüpft, wodurch ein besonders günstiger Wirkungsgrad erhalten wird.With this control, the principle of the series regulator is compared with that of the Linked step controller, whereby a particularly favorable efficiency is obtained.
