Abstract
(DE)
Bei einem Fahrzeugbordnetz mit einem Generator, dessen Erregerkreis von einem Spannungsregler beeinflußt wird, wobei neben einer ersten Spannungsebene von 12 Volt eine zweite höhere Spannungsebene vorgesehen ist, ist vorgesehen, daß diese durch eine Parallelschaltung mehrerer Chopperstufen realisiert ist, und daß die Spannungsregelung auf die erste, niedrigere Spannungsebene (U1) von 12V erfolgt.
(EN)
In a vehicle electrical system with a generator, the exciting circuit of which is affected by a voltage regulator, in which, besides a first 12 V voltage level, there is a second, higher, level, the latter takes the form of the parallel connection of several chopper stages and the voltage control takes place at the first lower voltage level (U1) of 12 V.
(FR)
L'invention concerne un réseau de bord pour véhicule comportant un générateur dont le circuit d'excitation est soumis à l'influence d'un régulateur de tension. Outre un premier niveau de tension de 12 volts, il est prévu un second niveau de tension, plus élevé. Il est prévu que le second niveau de tension consiste en une connexion en parallèle de plusieurs étages de découpage et que la régulation de la tension s'effectue sur le premier niveau de tension (U1) de 12 V qui est plus bas.
