Abstract

A generator has a claw pole machine with double-wired stator winding for AC with subsequent full-wave rectification and two slip rings for passing the excitation voltage to the rotor winding. At least two galvanically separated stator windings are provided. For them, at least two full-wave rectifiers for the generated system voltage are present. The excitation voltage of the rotor winding is passed from at least two parallel controllers via the slip rings. The voltage controllers (1,2) are designed according to the fail-safe principle and are supplied redundantly from both part- networks. The exciter winding of the generator is controlled via its own brush pair which sits on the slip rings.

Description

Die Erfindung betrifft einen Generator zur Speisung von Verbrauchern in Bordnetzen nach dem Oberbegriff des Anspruchs 1.The invention relates to a generator for supplying consumers in on-board electrical systems the preamble of claim 1.

Ausgehend von einer herkömmlichen Klauenpolmaschine als Kfz-Generator, die bereits eine zweidrähtige Statorwicklung aufweist, läßt sich mit geringfügigen Änderungen eine verbes­ serte Variante hinsichtlich einer sicheren Stromversorgung aufbauen. Hierbei wird von fol­ genden Eigenschaften Gebrauch gemacht:
Starting from a conventional claw pole machine as a motor vehicle generator, which already has a two-wire stator winding, an improved variant with regard to a secure power supply can be built up with minor changes. The following properties are used:

  • - Die in Klauenpolmaschinen eingesetzten Rotoren sind äußerst robust und nur in sehr seltenen Fällen Ursache eines Generatorausfalls.- The rotors used in claw pole machines are extremely robust and only very rare cause of generator failure.
  • - Die Statorwicklung kann aufgrund ihrer Isolation sowie ihrer Festigkeit durch Ver­ gießen ebenfalls als sehr zuverlässig betrachtet werden.- The stator winding can due to its insulation and its strength by Ver pour can also be regarded as very reliable.
  • - In Standard-Fahrzeuggeneratoren ist die Statorwicklung zweidrähtig ausgeführt. Zur Gleichrichtung sind in Hochleistungsgeneratoren generell bereits 12 Dioden einge­ baut.- In standard vehicle generators, the stator winding is two-wire. For Rectification is generally already using 12 diodes in high-performance generators builds.
  • - Häufigste Ausfallursache bei Generatoren ist ein Reglerdefekt.- The most common cause of failure in generators is a controller defect.

Der Erfindung liegt die Aufgabe zugrunde, zur Speisung von Verbrauchern in Bordnetzen für sicherheitskritische Anwendungen im Kfz einen Generator anzugeben, der eine hohe Zuverlässigkeit aufweist sowie eine getrennte Speisung zweier Teilnetze gestattet.The invention has for its object to supply consumers in electrical systems to specify a generator for safety-critical applications in motor vehicles which has a high Reliability and a separate supply of two subnets allowed.

Diese Aufgabe wird durch die im Kennzeichen des Anspruchs 1 aufgeführten Merkmale gelöst. Weiterführende und vorteilhafte Ausgestaltungen sind den weiteren Ansprüchen und der Beschreibung zu entnehmen.This object is achieved by the features listed in the characterizing part of claim 1 solved. Further and advantageous refinements are the further claims and see the description.

Die Erfindung wird nachstehend anhand der Zeichnung näher beschrieben. The invention is described below with reference to the drawing.  

Der Generator besteht aus den Statorwicklungen W1 und W2, die jeweils eine eigene Di­ odenbrücke B1 und B2 als Vorwellengleichrichter besitzen und die beiden Bordnetzspan­ nung UBN1 und UBN2 erzeugen. Die Dioden sind auch durch gesteuerte Halbleiter ersetzbar, so daß eine Kurzschluß-Abschaltung des jeweiligen Stranges erfolgen kann oder eine unsym­ metrische Leistungsaufteilung ermöglicht wird. Eine Erregerwicklung W und die Schleifrin­ ge S1, S2 sind aus den eingangs beschriebenen Gründen nur einfach ausgeführt. Getrennte Spannungsregler 1 und 2 sind nach dem sogen. fail-silent-Konzept ausgeführt und werden redundant aus beiden Teilnetzen versorgt. Über ein jeweils eigenes Bürstenpaar, das auf den Schleifringen S1, S2 aufsitzt, wird die Erregerwicklung W des Generators angesteuert.The generator consists of the stator windings W1 and W2, each of which has its own diode bridge B1 and B2 as a preliminary rectifier and generates the two electrical system voltages U BN1 and U BN2 . The diodes can also be replaced by controlled semiconductors, so that a short-circuit shutdown of the respective string can take place or an asymmetrical power distribution is made possible. An excitation winding W and the Schleifrin ge S1, S2 are only simple for the reasons described above. Separate voltage regulators 1 and 2 are based on the so-called. fail-silent concept and are supplied redundantly from both subnets. The excitation winding W of the generator is controlled via a separate pair of brushes, which are seated on the slip rings S1, S2.

Eine bevorzugte Ausgestaltung des erfindungsgemäßen Generators zur Speisung von Ver­ brauchern in Bordnetzen mit einer Klauenpolmaschine mit zweidrähtiger Statorwicklung für Drehstrom mit nachgeschalteter Vollwellengleichrichtung und zwei Schleifringen zur Zu­ führung der Erregungsspannung auf die Rotorwicklung besteht darin, daß mindestens zwei galvanisch getrennte Statorwicklungen (W1, W2) vorgesehen sind, daß für sie mindestens zwei Vollwellengleichrichter (B1, B2) für die aus Drehstrom erzeugten Bordnetzspannungen (UBN1 UBN2) vorhanden sind, daß die Erregungsspannung der Rotorwicklung (W) von minde­ stens zwei parallelgeschalteten Reglern (R1, R2) über die Schleifringe (S1 und S2) zugeführt wird, die Spannungsregler (1 und 2) nach dem "fail-silent"-Konzept ausgeführt und redun­ dant aus beiden Teilnetzen versorgt sind, und daß die Erregerwicklung des Generators über ein jeweils eigenes Bürstenpaar, das auf den Schleifringen aufsitzt, angesteuert ist. Dadurch bleibt bei Ausfall eines Reglers oder einer Bordnetzspannung die Leistungsversorgung des anderen Bordnetzes voll erhalten.A preferred embodiment of the generator according to the invention for supplying consumers in vehicle electrical systems with a claw-pole machine with a two-wire stator winding for three-phase current with subsequent full-wave rectification and two slip rings for supplying the excitation voltage to the rotor winding consists in that at least two electrically isolated stator windings (W1, W2) are provided are that there are at least two full-wave rectifiers (B1, B2) for the on-board electrical system voltages (U BN1 U BN2 ) that the excitation voltage of the rotor winding (W) of at least two parallel-connected regulators (R1, R2) via the slip rings (S1 and S2) is supplied, the voltage regulators ( 1 and 2 ) are designed according to the "fail-silent" concept and are redundantly supplied from both sub-networks, and that the excitation winding of the generator has its own pair of brushes on the slip rings sits on, is controlled. As a result, the power supply of the other electrical system is fully retained in the event of a controller or an electrical system voltage failure.

Eine vorteilhafte Ausgestaltung ist, daß Gleichrichter der Vollwellengleichrichter (B1, B2) gesteuerte Halbleiter sind, die derart gesteuert sind, daß bei Kurzschluß eine Abschaltung des jeweiligen Stranges erfolgt oder eine unsymmetrische Leistungsaufteilung erreicht ist.An advantageous embodiment is that rectifiers of the full-wave rectifiers (B1, B2) are controlled semiconductors which are controlled such that a shutdown in the event of a short circuit of the respective line takes place or an asymmetrical power distribution is achieved.

AnwendungsbeispielApplication example

Besonders bevorzugt ist der Einsatz eines erfindungsgemäßen Generators bei Fahrzeugen mit sogen. steer-by-wire oder sogen. brake-by-wire Systemen, welche besonders sichere Bordnetze benötigen, die vorzugsweise zweikreisig aufgebaut sind. Zur getrennten, rückwir­ kungsfreien Versorgung beider Netze lassen sich derartige Generatoren einsetzen.The use of a generator according to the invention in vehicles is particularly preferred with so-called steer-by-wire or so-called. brake-by-wire systems that are particularly safe  Need electrical systems, which are preferably constructed in two circuits. For separate, retroactive Generators of this type can be used without supplying both networks.
