Title
(DE) VORRICHTUNG ZUR SPANNUNGSVERSORGUNG FÜR EIN KRAFTFAHRZEUG-BORDNETZ

Abstract
(DE) Es wird eine Vorrichtung zur Spannungsversorgung für ein Kraftfahrzeug-Bordnetz mit einem permanenterregten Generator (11) vorgeschlagen, bei dem eine Spannungsregelung auch im batterielosen Betrieb möglich ist. Dazu wird der Spannungsregler (15), der den gesteuerten Brückengleichrichter (16, 17, 18) steuert, über Hilfsdioden (22, 23, 24) zusätzlich mit Spannung versorgt, so dass der Spannungsregler (15) auch bei gesperrten Leistungshalbleitern des Brückengleichrichters aus dem Generator mit Spannung versorgt wird. Die beim batterielosen Betrieb auftretenden Spannungsspitzen werden über eine Zenerdiode (25) abgeführt, so dass ein Überspannungsschutz jederzeit gewährleistet ist.
(EN) 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.
(FR) Dispositif d'alimentation en courant du réseau de bord d'un véhicule automobile, présentant une génératrice à excitation permanente (11), et dans lequel un réglage de tension est possible, même pour un fonctionnement en l'absence de batterie. A cet effet le régulateur de tension (15) commandant les redresseurs à pont (16, 17, 18) asservis est également alimenté, par l'intermédiaire de diodes auxiliaires (22, 23, 24), en tension de façon que le régulateur de tension (15) soit alimenté par la génératrice, même en cas de fermeture des semi-conducteurs de puissance du redresseur à pont. Les pointes de tension se présentant lors du fonctionnement sans batterie sont éliminées par l'intermédiaire d'une diode Zener (25), permettant ainsi d'obtenir à tout moment une protection contre les surtensions.
