Title (EN) REGULATED POWER SUPPLY
(FR) ALIMENTATION RÉGULÉE
Abstract:
(EN) Current regulating techniques utilizing buck-boost circuitries are disclosed. A buck switching device is used in an input stage of a buck-boost circuitry of some embodiments for regulating an input current thereof, and a boost switching device is used in an output stage thereof. A control system is used to set the buck switching device into a closed state at a beginning of each cycle of a periodic timing signal, and open the buck switching device to cause the input current to converge towards a defined target current value, while an unrelated controller changes in each cycle the boost switching device into an open state based on an input/output dependent force-on duty cycle value, and thereafter change the boost switching device back into the closed state whenever the output current of the boost circuit drops below a determined threshold current value.
(FR) L'invention concerne des techniques de régulation de courant utilisant des circuits survolteur-dévolteur. Un dispositif de commutation de type survolteur est utilisé dans un étage d'entrée d'un circuit survolteur-dévolteur de certains modes de réalisation pour réguler un courant d'entrée associé, et un dispositif de commutation survolteur est utilisé dans un étage de sortie associé. Un système de commande est utilisé pour régler le dispositif de commutation de type survolteur dans un état fermé au début de chaque cycle d'un signal de synchronisation périodique, et pour ouvrir le dispositif de commutation de type survolteur pour amener le courant d'entrée à converger vers une valeur de courant cible définie, tandis qu'un dispositif de commande indépendant change dans chaque cycle le dispositif de commutation de suralimentation dans un état ouvert sur la base d'une valeur de cycle de service dépendant de la force d'entrée/sortie, et par la suite le changement du dispositif de commutation de suralimentation dans l'état fermé à chaque fois que le courant de sortie du circuit d'amplification chute au-dessous d'une valeur de courant de seuil déterminée.
