Abstract

Modulateur modulaire (10) à un étage pour sources d'éclairage pulsées, utilisant un convertisseur (20) à pont intégral qui convertit un courant continu non stabilisé en une porteuse de 40 à 50 kHz modulée à une fréquence allant de quelques centaines à quelques milliers de hertz. Cette porteuse modulée est appliquée à la source d'éclairage (66) par l'intermédiaire d'un transformateur (50) dévolteur suivi d'un circuit (60) à filtre passe-bas qui supprime la porteuse. Le convertisseur (20) est piloté par une commande de modulation (42) qui emploie une réaction (72) de signal de courant de charge instantanée pour suivre un signal (74) de commande de modulation, ainsi qu'un signal (76) de mode de courant représentant le courant primaire du transformateur (50) pour compenser les variations de sortie du convertisseur, provoquées par des variations de la tension d'entrée.
