Abstract

The proposal is for a device for powering a vehicle's electrical system with a permanently excited generator (11) where voltage control is possible even during batteryless operation. To this end the voltage control device (15) which controls the regulated bridge rectifier (16, 17, 18) is additionally powered via auxiliary diodes (22, 23, 24) so that said voltage control device (15) receives power from the generator even when the power semiconductors are blocked. The voltage peaks occurring during batteryless operation are deviated via a Zener diode (25), thus providing overvoltage protection at all times.

Vorrichtung zur Spannungsversorounσ für ein Kraftfahrzeuo-BordnetzDevice for voltage supply for a motor vehicle electrical system
Stand der TechnikState of the art
Die Erfindung geht aus von einer Vorrichtung zur Spannungsversorgung für ein Kraftfahrzeug-Bordnetz nach der Gattung des Hauptanspruchs. In solchen Vorrichtungen zur Spannungsversorgung, die als Generator einen permanentmagneterregten Generator enthalten, kann die Span¬ nungsregelung auf verschiedene Weise erfolgen. Eine Möglichkeit ist, einen Längsregler vorzusehen mit einem Hauptstromschalter im Längs¬ zweig, eine weitere Möglichkeit ist eine Querregelung mit einem Hauptstromschalter im Querzweig.. Auch die Kombination von beiden Re¬ gelarten ist möglich. Bei den bisher bekannten Systemen können je¬ doch Spannungsspitzen insbesondere in dem Fall, in dem das System ohne Batterie betrieben wird, zur Zerstörung von empfindlichen Bau¬ elementen führen.The invention relates to a device for power supply for a motor vehicle electrical system according to the preamble of the main claim. In such devices for voltage supply, which contain a permanent magnet-excited generator as a generator, the voltage regulation can take place in different ways. One possibility is to provide a series regulator with a main current switch in the series branch, a further possibility is cross-regulation with a main current switch in the cross branch. The combination of both control types is also possible. In the previously known systems, however, voltage peaks can lead to the destruction of sensitive components, in particular in the case in which the system is operated without a battery.
Aus der DE-OS 30 36 092 ist ein Batterieladesystem mit einem per¬ manenterregten Generator bekannt, mit einem Spannungsregler, der eine Zenerdiode zur Spannungsbegrenzung umfaßt, welche zwischen dem Generatorausgang und Masse geschaltet ist und die Spannungsspitzen, die insbesondere im Betrieb ohne Batterie auftreten können, abführt. From DE-OS 30 36 092 a battery charging system with a permanently excited generator is known, with a voltage regulator, which comprises a zener diode for voltage limitation, which is connected between the generator output and ground, and the voltage peaks, which can occur in particular in operation without a battery , leads away.
Das bekannte Batterieladesystem hat jedoch den Nachteil, daß die Gleichrichterelemente der Drehstrombrucke nicht gesteuert werden.However, the known battery charging system has the disadvantage that the rectifier elements of the three-phase bridge are not controlled.
Solche gesteuerten Drehstrombrücken sind zwar auch im Zusammenhang mit einem permanentmagneterregten Generator und einem Spannungs¬ regler bekannt, beispielsweise aus der DE-OS 30 09 278, jedoch weist diese vorbekannte Schaltungsanordnung keine Zenerdiode zum Über¬ spannungsschutz auf und ist daher nicht für einen Betrieb ohne Bat¬ terie geeignet. Außerdem wird der Regler bei gesperrten Gleichrich¬ terelementen der gesteuerten Drehstrombrucke vom Generator nicht mit Spannung versorgt, so daß der Spannungsregler bei Betrieb ohne Bat¬ terie überhaupt nicht mehr mit Spannung versorgt würde.Such controlled three-phase bridges are also known in connection with a permanent magnet-excited generator and a voltage regulator, for example from DE-OS 30 09 278, but this known circuit arrangement has no zener diode for overvoltage protection and is therefore not suitable for operation without a bat ¬ suitable. In addition, the regulator is not supplied with voltage by the generator when the rectifier elements of the controlled three-phase current bridges are blocked, so that the voltage regulator would no longer be supplied with voltage when operating without battery.
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Vorrichtung zur Spannungsversorgung für ein Kraftfahrzeug-Bordnetz mit den kennzeichnenden Merkmalen des Haupt¬ anspruchs und der Nebenansprüche hat gegenüber dem Bekannten den Vorteil, daß mittels eines Hilfsdiodentrios der Spannungsregler auch bei gesperrten Leistungshalbleitern der Gleichrichterbrücke direkt aus dem Generator mit Spannung versorgt wird und damit auch nach einem Öffnen des Batterieanschlusses (beabsichtigt oder durch Lei¬ tungsbruch bedingt) mit Spannung versorgt bleibt. Ein Betrieb des Reglers und damit eine Steuerung der Drehstrombrucke und die Ver¬ sorgung des Bordnetzes ist daher auch ohne Batterie möglich.The device according to the invention for the voltage supply for a motor vehicle electrical system with the characterizing features of the main claim and the subsidiary claims has the advantage over the known that the voltage regulator is supplied with voltage directly from the generator even with blocked power semiconductors of the rectifier bridge by means of an auxiliary diode trio, and thus remains supplied with voltage even after the battery connection has been opened (intentionally or as a result of a line break). Operation of the controller and thus control of the three-phase current bridge and the supply of the vehicle electrical system is therefore also possible without a battery.
Weiterhin ist besonders vorteilhaft daß über die Leistungszener- diode auch kurzzeitig auftretende Spannungsspitzen abgeleitet werden können, bevor der Regler eingreift und die Leistungshalbleiter sperrt. Weiterhin ist vorteilhaft, daß die Leistungszenerdiode bei batterielosem Betrieb als Freilaufdiode wirkt. ZeichnungFurthermore, it is particularly advantageous that voltage peaks occurring briefly can also be derived via the power zener diode before the controller intervenes and blocks the power semiconductors. It is also advantageous that the power zener diode acts as a freewheeling diode during battery-free operation. drawing
Ein Ausführungsbeispiel der Erfindung ist in der Figur dargestellt und in der nachfolgenden Beschreibung näher erläutert.An embodiment of the invention is shown in the figure and explained in more detail in the following description.
Beschreibung der AusführungsbeispieleDescription of the embodiments
Die Figur zeigt einen permanenterregten Dreiphasengenerator 11, dem eine halb gesteuerte Gleichrichterbrücke 12 nachgeschaltet ist. Die Ausgangsleistung steht am Generatorausgang 13 für das nachfolgende Bordnetz zur Verfügung. Zwischen Den Generatorausgang 13 und Masse 14 ist ein Spannungsregler 15 geschaltet, der mit den steuerbaren Gleichrichterelementen, beispielsweise Halbleiterelementen 16, 17 und 18 der Gleichrichterbrücke 12, die außerdem noch die Gleich¬ richterelemente 19, 20, 21 umfaßt, verbunden ist und außerdem über drei Zusatzdioden 22, 23 und 24 mit der Gleichrichterbrücke und je¬ weils einer der drei Phasenwicklungen des Generators 11 verbunden ist. Zwischen den Generatorausgang 13 und Masse 14 ist eine Paral¬ lelschaltung, bestehend aus einer Zenerdiode 25, üblicherweise einer Leistungszenerdiode, gegebenenfalls einer Batterie 26 und verschie¬ denen Verbrauchern, 27, 28, geschaltet. Dabei sind zur Batterie 26 und den Verbrauchern 27 und 28 jeweils Schalter 29, 30 und 31 in Serie geschaltet. Zwischen dem Verbindungspunkt 32 der Zenerdiode 25 mit dem Generatorausgang 13 und die Schalter 29, 30, 31 kann eine Zusatzdrossel 33 geschaltet werden.The figure shows a permanently excited three-phase generator 11, which is followed by a semi-controlled rectifier bridge 12. The output power is available at generator output 13 for the subsequent electrical system. Between the generator output 13 and ground 14, a voltage regulator 15 is connected, which is connected to the controllable rectifier elements, for example semiconductor elements 16, 17 and 18 of the rectifier bridge 12, which also includes the rectifier elements 19, 20, 21 and also via three Additional diodes 22, 23 and 24 are connected to the rectifier bridge and one of the three phase windings of the generator 11. A parallel circuit, consisting of a zener diode 25, usually a power zener diode, possibly a battery 26 and various consumers 27, 28, is connected between the generator output 13 and ground 14. Switches 29, 30 and 31 are connected in series to the battery 26 and the consumers 27 and 28, respectively. An additional choke 33 can be connected between the connection point 32 of the Zener diode 25 with the generator output 13 and the switches 29, 30, 31.
Die Gleichrichterelemente 16, 17 und 18 der Gleichrichterbrücke 12 sind im Ausführungsbeispiel als Thyristoren ausgebildet, die Gleich¬ richterelemente 19, 20, 21 sind im Ausführungsbeispiel Dioden. Es ist jedoch auch möglich, die Gleichrichterelemente 19, 20 und 21 ebenfalls als Thyristoren auszubilden und sie entsprechend den Thyristoren 16, 17 und 18 mit dem Spannungsregler zu verbinden und somit eine voll gesteuerte Gleichrichterbrücke zu erhalten. Die Hilfsdioden 22, 23 und 24 können auch als Zenerdioden ausgebil¬ det sein.The rectifier elements 16, 17 and 18 of the rectifier bridge 12 are designed as thyristors in the exemplary embodiment, the rectifier elements 19, 20, 21 are diodes in the exemplary embodiment. However, it is also possible to also design the rectifier elements 19, 20 and 21 as thyristors and to connect them to the voltage regulator in accordance with thyristors 16, 17 and 18 and thus to obtain a fully controlled rectifier bridge. The auxiliary diodes 22, 23 and 24 can also be designed as Zener diodes.
Anstelle der Zenerdiode 25 kann auch eine andere Vorrichtung zum Überspannungsschutz vorgesehen werden.Instead of the Zener diode 25, another device for overvoltage protection can also be provided.
Mit der in der Figur gezeigten Schaltungsanordnung wird der vom Per¬ manentfeldgenerator gelieferte Strom über die halb gesteuerte Gleichrichterbrücke 12 gleichgerichtet und ins Netz abgegeben. Der Spannungsregler 15 sorgt dafür, daß die AusgangsSpannung des Genera¬ tors unabhängig von den Betriebsbedingungen des Generators konstant gehalten wird. Dazu werden die Thyristoren 16, 17 und 18 gesperrt, wenn die Spannung an Klemme 13 über einen vorgegebenen Wert steigt und leitend gemacht, wenn die Spannung am Gleichleistungsausgang 13 unter einen vorgegebenen Wert fällt. Dabei erfolgt die Ansteuerung der Thyristoren durch den Spannungsregler nach einer an sich bekann¬ ten Phasenanschnittsteuerung oder nach der ebenfalls bekannten Puls¬ paketmethode.With the circuit arrangement shown in the figure, the current supplied by the permanent field generator is rectified via the semi-controlled rectifier bridge 12 and released into the network. The voltage regulator 15 ensures that the output voltage of the generator is kept constant regardless of the operating conditions of the generator. For this purpose, the thyristors 16, 17 and 18 are blocked when the voltage at terminal 13 rises above a predetermined value and made conductive when the voltage at DC output 13 falls below a predetermined value. The thyristors are controlled by the voltage regulator according to a phase control control known per se or according to the likewise known pulse packet method.
Die drei Hilfsdioden 22, 23 und 24 und die Leistungszenerdiode 25 ermöglichen einen batterielosen Betrieb des Kraftfahrzeugs.The three auxiliary diodes 22, 23 and 24 and the power zener diode 25 enable battery-free operation of the motor vehicle.
Die Leistungszenerdiode 25 bewirkt bei absichtlicher Öffnung des Batterieanschlusses oder bei durch Leitungsbruch verursachter Öff¬ nung des Batterieanschlusses einen Schutz des Bordnetzes gegen kurz¬ zeitige Spannungsspitzen, solange, bis der Regler eingreift und die Leistungshalbleiter sperrt. Außerdem wirkt die Leistungszenerdiode 25 bei batterielosem Betrieb als Freilaufdiode für das Bordnetz.When the battery connection is opened deliberately or the battery connection is opened due to a wire break, the power zener diode 25 protects the vehicle electrical system against brief voltage peaks until the controller intervenes and blocks the power semiconductors. In addition, the power zener diode 25 acts as a freewheeling diode for the on-board electrical system in the case of battery-free operation.
Sind die Leistungshalbleiter des Brückengleichrichters gesperrt, so erhält der Spannungsregler 15 über die drei Hilfsdioden 22, 23 und 24 die Spannung direkt aus dem Generator. Damit ist ein batterieloser Betrieb der Vorrichtung zur Spannungs¬ versorgung möglich, da auch nach Sperren der als Leistungshalbleiter 16, 17 und 18 eine Steuerung der Gleichrichterbrücke über den Span¬ nungsregler erfolgen kann_und dami die Versorgung des Bordnetzes ermöglicht werden kann. If the power semiconductors of the bridge rectifier are blocked, the voltage regulator 15 receives the voltage directly from the generator via the three auxiliary diodes 22, 23 and 24. This enables battery-free operation of the device for the voltage supply, since even after the power semiconductors 16, 17 and 18 have been blocked, the rectifier bridge can be controlled via the voltage regulator, and thus the supply of the on-board electrical system can be made possible.
