Title
(EN) IMPROVED VOLTAGE REGULATION APPARATUS
(FR) APPAREIL DE RÉGULATION DE TENSION AMÉLIORÉ
Abstract
(EN)
A voltage regulator for regulation both of AC and of DC voltages, is provided in a regulator module (30) which uses a repetitive switching signal (32) to control a switch (36) allowing current to be supplied to a reservoir capacitor (42) by supply from an unregulated rail (18). The module contains a dual inductor (44, 46, 48) having first (44) and second (46) identical windings and a common core. A current pass capacitor (43) is also provided. When the switch (36) is closed, the first winding (44) delivers current to the reservoir capacitor. When the switch (36) is open, both the second (44) and the first (46) windings deliver current to the reservoir capacitor (42). The apparatus can support balanced operation, where pairs of switches are operated alternately and oppositely. The switching signal (32) can be suitably voltage restored to provide a signal suitable to control and operates switches (36). Different configurations of transistor switches (36) and diodes (38) are shown.

La présente invention concerne un régulateur de tension destiné à réguler les tensions alternative et continue, disposé dans un module de régulateur (30) utilisant un signal de commutation répétitif (32) pour commander un commutateur (36) permettant au courant d'être apporté à un condensateur de filtrage (42) par apport provenant d'un rail non régulé (18). Le module contient une double bobine d'induction (44, 46, 48) présentant des premier (44) et second (46) enroulements identiques et un noyau commun. Un condensateur de passage de courant (43) est également fourni. Lorsque le commutateur (36) est fermé, le premier enroulement (44) fournit du courant au condensateur de filtrage. Lorsque le commutateur (36) est ouvert, les second (44) et premier (46) enroulements fournissent du courant au condensateur de filtrage (42). L'appareil peut supporter une alimentation symétrique, dans laquelle les paires de commutateurs sont actionnées en alternance et de manière opposée. Le signal de commutation (32) peut être restauré avec une tension appropriée pour fournir un signal adapté à commander et à faire fonctionner des commutateurs (36). Différentes configurations de commutateurs à transistor (36) et de diodes (38) sont illustrées.
