Abstract

The battery powered generator has power MOS transistor modules (1-3) in parallel, which are energised via a common clock pulse generator via e.g. a reed relay. Their control inputs are resistively coupled to their common output. The modules are pref. mounted next to each other on a heat conductive assembly support (25). The modules are in thermal contact with the support and their battery voltage terminals, their control inputs and outputs coupled in parallel by linking rails (13 - 15), mutually parallel and electrically insulated, with two rails (13, 15) in vertical extension. The vertically extending rails are both engaged by respective terminal screws (26, 27), using insulating intermediate layers (32). ADVANTAGE - Compact design, adaptable to different current amplitudes or reliability requirements.

Description

Die Erfindung betrifft eine batteriespannungsgespeiste Vorrich­ tung gemäß dem Oberbegriff des Patentanspruchs 1. Insbesondere soll diese Vorrichtung zur Erzeugung getakteter hoher Gleich­ ströme in der Größenordnung von 600 A in Kraftfahrzeugen dienen, deren Abgaßanlagen mit heizbaren Katalysatoren bestückt sind. Bekanntlich sind derartige Abgaskatalysatoren erst nach Er­ reichen einer bestimmten Mindesttemperatur voll wirksam, und es ist bekannt, beim Kaltstart kleinvolumige Vorkatalysatoren auf elektrischem Wege zwecks Erzielung einer schnellen Wirksamkeit aufzuheizen.The invention relates to a battery-powered device tion according to the preamble of claim 1. In particular this device is intended to generate clocked high equals currents of the order of 600 A are used in motor vehicles, whose exhaust systems are equipped with heatable catalysts. Such exhaust gas catalysts are known only after Er range a certain minimum temperature fully effective, and it is known to have small-volume pre-catalysts on cold start electrical way to achieve quick effectiveness to heat up.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, eine gat­ tungsgemäße Vorrichtung zu schaffen, die sich durch gedrängte Bauweise, Erweiterungsfähigkeit zwecks Anpassung an die jeweils erforderliche Höhe des Gleichstroms und Betriebssicherheit aus­ zeichnet.The invention is therefore based on the object, a gat to create device in accordance with the crowded Construction, expandability to adapt to each required level of direct current and operational safety draws.

Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kenn­ zeichnenden Merkmalen des Hauptanspruchs, vorteilhafte Ausbil­ dungen der Erfindung beschreiben die Unteransprüche.The inventive solution to this problem consists in the drawing features of the main claim, advantageous training The invention describes the subclaims.

Während Anspruch 1 im wesentlichen elektrische Merkmale der Vor­ richtung betrifft, beinhalten die Unteransprüche vorteilhafte mechanische Ausbildungen derselben. Durch die elektrischen An­ spruchsmerkmale ist sichergestellt, daß die Steuereingänge der Moduln, wie erforderlich, eine um beispielsweise 5 bis 15 V höhere Spannung erhalten als die Ausgangsspannung der Vorrich­ tung. Dies wird erreicht durch eine potentialfreie Ansteuerung der Moduln beispielsweise über einen Reed-Kontakt oder eine elektronische taktweise Ansteuerung. Bei Verwendung eines Gleichspannungswandlers ist auch sichergestellt, daß bei ver­ ringerter Batteriespannung noch die erforderliche Ausgangs­ spannung zur Verfügung steht. Die Widerstandsverbindungen zwi­ schen den Steuereingängen der Moduln einerseits und dem gemein­ samen Ausgang andererseits verhindern eine Selbstzerstörung der Bauteile bei geöffnetem Reed-Kontakt (bzw. bei einem entspre­ chenden Zustand eines anderen Taktgebers), indem sie die Steuer­ eingänge dann auf Nullpotential legen.While claim 1 essentially electrical features of the front Direction concerns, the sub-claims contain advantageous mechanical training of the same. Through the electrical connection characteristics is ensured that the control inputs of the Modules, as required, a 5 to 15 V, for example  receive higher voltage than the output voltage of the Vorrich tung. This is achieved through a potential-free control of the modules, for example via a reed contact or a electronic cyclical control. When using a DC converter is also ensured that at ver reduced battery voltage still the required output voltage is available. The resistance connections between between the control inputs of the modules on the one hand and the common on the other hand prevent the self - destruction of Components with the reed contact open (or with a corresponding state of another clock) by the tax then set inputs to zero potential.

Wie die Unteransprüche zum Ausdruck bringen, bietet die erfin­ dungsgemäße Vorrichtung auch den Vorteil eines besonders ge­ drängten Aufbaus auch unter Wahrung der erforderlichen Wärmeab­ fuhr von den Moduln.The inventor offers how to express the subclaims device according to the invention also has the advantage of a particularly ge pushed construction even while maintaining the required heat drove from the modules.

Die Erfindung wird im folgenden anhand der Ausführungsbeispiele wiedergebenden Zeichnung erläutert. Dabei zeigt Fig. 1 im we­ sentlichen die elektrische Schaltung, während sich die weiteren Figuren auf die konstruktive Ausgestaltung der Vorrichtung be­ zieht.The invention is explained below with reference to the drawing showing the exemplary embodiments. Here, FIG. 1 shows in we sentlichen the electric circuit, while the other figures on the structural design of the device, draws be.

In Fig. 1 erkennt man drei handelsübliche Power-MOS-Transistor- Moduln 1, 2 und 3, deren Batteriespannungseingänge 4, 5 und 6, deren Ausgänge 7, 8 und 9 und deren Steuereingänge 10, 11 und 12 über jeweils eine beispielsweise aus Messing bestehende Verbin­ dungsschiene 13, 14 und 15 parallel geschaltet sind. Wie bei 16 angedeutet, läßt sich diese Vorrichtung in einfacher Weise durch Hinzufügen bzw. Entfernen von Moduln an unterschiedliche Strom­ erfordernisse zu versorgender Verbraucher, hier von vorheizbaren Abgaskatalysatoren 17, anpassen.In Fig. 1 you can see three commercially available power MOS transistor modules 1 , 2 and 3 , their battery voltage inputs 4 , 5 and 6 , their outputs 7 , 8 and 9 and their control inputs 10 , 11 and 12 each have a brass, for example existing connec tion rail 13 , 14 and 15 are connected in parallel. As indicated at 16 , this device can be easily adapted by adding or removing modules to different current requirements to be supplied to consumers, here of preheatable catalytic converters 17 .

Der Gleichspannungswandler 18, der von der Batterie mit der Batteriespannung UB über einen Spannungsbegrenzer versorgt wird, dient dazu, auch bei abgefallener Batteriespannung eine Spannung V zwischen den Steuereingängen 10, 11 und 12 einerseits und den Ausgängen 7, 8 und 9 andererseits sicherzustellen, die um einen zum Betrieb der Moduln 1, 2 und 3 erforderlichen Wert, bei­ spielsweise 5 bis 15 V, höher ist als die Ausgangsspannung. Ferner sichert die Zuführung der Steuerspannung zu den Steuer­ eingängen 10, 11 und 12 über das taktweise arbeitende Reed- Relais 19 mit seinem Kontakt 20 eine potentialfreie Ansteuerung der Moduln 1, 2 und 3, wobei ferner zwischen den Steuereingängen 10, 11 und 12 einerseits und den Ausgängen 7, 8 und 9 anderer­ seits Widerstände 21, 22 und 23 von beispielsweise 1 kΩ Gesamt­ widerstand der Parallelschaltung enthaltende Verbindungen be­ stehen, die bei offenem Relaiskontakt 20 die Eingänge auf Null­ potential legen und damit eine Zerstörung der Bauteile verhin­ dern.The DC-DC converter 18 , which is supplied by the battery with the battery voltage U B via a voltage limiter, serves to ensure a voltage V between the control inputs 10 , 11 and 12 on the one hand and the outputs 7 , 8 and 9 on the other hand, even when the battery voltage has dropped by a value required for the operation of modules 1 , 2 and 3 , for example 5 to 15 V, is higher than the output voltage. Furthermore, the supply of the control voltage to the control inputs 10 , 11 and 12 via the cyclically operating reed relay 19 with its contact 20 ensures a potential-free control of the modules 1 , 2 and 3 , furthermore between the control inputs 10 , 11 and 12 on the one hand and the outputs 7 , 8 and 9 on the other hand resistors 21 , 22 and 23 of, for example, 1 kΩ total resistance of the parallel circuit containing connections are available, which set the inputs to zero potential when the relay contact 20 is open and thus prevent destruction of the components.

Zu ergänzen ist, daß das Reed-Relais 19 über den Steuereingang 24 taktweise von einem Controller angesteuert wird.It should be added that the reed relay 19 is actuated in cycles by a controller via the control input 24 .

Betrachtet man nun anhand der Fig. 2, 3 und 4 den konstruk­ tiven Aufbau der Vorrichtung (in diesen Figuren sind die bereits in Fig. 1 vorkommenden Bezugszeichen übernommen), so sind die Moduln 1, 2 und 3 nebeneinander in einer Reihe auf dem aus wär­ meleitendem Material stehenden Montageträger oder Montageklotz 25 beispielsweise durch Verschrauben unter Zwischenfügen von Wärmeleitpaste festgelegt. Der Montageträger 25 seinerseits steht beispielsweise in wärmeleitender Verbindung mit einem Kühlkörper eines Gehäuses. Wie insbesondere die Fig. 2 (in Seitenansicht) und 3 (in Draufsicht) zeigen, verlaufen die Ver­ bindungsschienen 13, 14 und 15 parallel und die beiden Schienen 13 und 15 übereinander. Diese gedrängte Bauweise erfordert ver­ ständlicherweise zusätzliche Maßnahmen im Bereich der übereinan­ der verlaufenden Verbindungsschienen 13 und 15, die unerwünschte elektrische Verbindungen ausschließen. Dies ist im Bereich des Moduls 1 in Fig. 1 dargestellt: Man erkennt, daß beide Verbin­ dungsschienen 13 und 15 von Anschlußschrauben 26 und 27 des Moduls 1 durchsetzt sind, die jeweils zur Herstellung einer elektrischen Verbindung mit nur einer der Verbindungsschienen 13 und 15 dienen sollen. Aus diesem Grunde sind die Schienen 13 und 15 in abwechselnder Folge mit Schraubendurchgangslöchern 28, 29 und 30, 31 unterschiedlichen Durchmessers versehen, von denen die Löcher 28 und 31 kleineren Durchmessers so bemessen sind, daß sie elektrischen Kontakt mit der jeweiligen Verbindungs­ schiene 13 bzw. 15 herstellen, während die Durchgangslöcher 29 und 30 größeren Durchmessers so ausgelegt sind, daß in ihnen Isolierhülsen 32 und 33 untergebracht werden können. Diese Isolierhülsen, die auch von Isolierzwischenlagen 34 und 35 umgeben sind bzw. derartige isolierende Abstandsglieder zwischen den Schienen 13 und 15 bildende Bereiche aufweisen, verhindern demgemäß unerwünschte elektrische Kontakte zwischen den Schienen einerseits und den Anschlußschrauben andererseits.If one now looks at FIGS . 2, 3 and 4, the constructive structure of the device (in these figures, the reference numerals already appearing in FIG. 1 are adopted), the modules 1 , 2 and 3 are next to each other in a row on the heat-conducting material standing mounting bracket or mounting block 25, for example, by screwing with the interposition of thermal paste. The mounting bracket 25 in turn is, for example, in heat-conducting connection with a heat sink of a housing. As shown particularly in Fig. 2 show (in side view) and 3 (in plan view), which run Ver connection rails 13, 14 and 15 in parallel, and the two rails 13 and 15 over each other. This compact design understandably requires additional measures in the area of the overlapping connecting rails 13 and 15 , which exclude unwanted electrical connections. This is illustrated in the section of the module 1 in Fig. 1: It is seen that both Verbin dung rails are penetrated by connection screws 26 and 27 of the module 1 13 and 15, which each serve for making an electrical connection with only one of the connection rails 13 and 15 should. For this reason, the rails 13 and 15 are provided in alternating sequence with screw through holes 28 , 29 and 30 , 31 of different diameters, of which the holes 28 and 31 of smaller diameter are dimensioned such that they make electrical contact with the respective connecting rail 13 or 15 produce, while the through holes 29 and 30 of larger diameter are designed so that insulating sleeves 32 and 33 can be accommodated in them. These insulating sleeves, which are also surrounded by insulating intermediate layers 34 and 35 or have such insulating spacers between the rails 13 and 15 forming areas, accordingly prevent undesired electrical contacts between the rails on the one hand and the connecting screws on the other.

Die ebenfalls von dem Montageträger 25 getragenen Gewindebolzen 36 und 37 dienen der Herstellung der Verbindungen zwischen der in den Fig. 2, 3 und 4 dargestellten Baueinheit und dem rest­ lichen Teil der in Fig. 1 wiedergegebenen Schaltung.The also carried by the mounting bracket 25 threaded bolts 36 and 37 serve to establish the connections between the unit shown in FIGS. 2, 3 and 4 and the rest of the part of the circuit shown in Fig. 1.

Mit der Erfindung ist demgemäß eine gattungsgemäße Einrichtung geschaffen, die mit einfachen Mitteln eine hohe Betriebssicher­ heit, eine leichte Anpaßbarkeit an den jeweiligen Einsatzfall sowie eine platzsparende Bauweise gewährleistet.With the invention is accordingly a generic device created a high level of operational reliability with simple means unit, easy adaptability to the respective application as well as a space-saving construction guaranteed.
