The present invention provides shunt voltage regulation by employing a rectifying means (M1-M4) to rectify an incoming signal and a current sinking means (M5-M6) to divert current from the output (o) of the rectifying means in such a way that the output voltage is maintained at an appropriate level and the modulation level does not rise above the acceptable range. This is accomplished by having two feedback mechanisms for the control of said current sinking means. A first feedback mechanism (G) utilizes a voltage dividing means (R6-R7) to generate a control voltage signal that will cause the average output voltage of the rectifying means to be equal to the a reference voltage. A second feedback mechanism utilizes non-linear processing means (NLP; Fig. 7) and capacitors (C3-C4) to transmit part of the modulation frequency to the control (M7-M14, R2-R5) of the current sinking means, thereby keeping the modulation at the output of the rectifying mean at an appropriate level at all time.

la présente invention concerne une régulation de tension shuntée faisant intervenir des dispositifs redresseurs (M1-M4) pour redresser un signal entrant et des dispositifs d'absorption de courant (M5-M6) destinés à dévier le courant de la sortie (o) des dispositifs redresseurs de manière à maintenir la tension de sortie à un niveau approprié et à empêcher le niveau de modulation de dépasser une plage acceptable. A cette fin, on utilise deux mécanismes de rétroaction pour commande desdits dispositifs d'absorption de courant. Un premier dispositif de rétroaction (G) recourt à des dispositifs diviseurs de tension (R6-R7) pour produire un signal de commande de tension qui rend la tension de sortie moyenne des dispositifs redresseurs égale à la tension de référence. Un second mécanisme de rétroaction fait appel à des dispositifs de traitement non linéaires (NLP; Fig. 7) et à des condensateurs (C3-C4) pour la transmission d'une partie de la modulation de fréquence à la commande (M7-M14, R2-R5) des dispositifs d'abaissement d'intensité, ce qui permet de maintenir la modulation de la sortie des dispositifs redresseurs en permanence à un niveau approprié.
