Title (EN) FEEDBACK GAIN ADJUSTMENT TO ENHANCE STABILITY OF SWITCHING CONVERTER WITH VARIABLE OUTPUT VOLTAGE
(FR) RÉGLAGE DE GAIN DE RÉTROACTION POUR AMÉLIORER LA STABILITÉ D'UN CONVERTISSEUR DE COMMUTATION AYANT UNE TENSION DE SORTIE VARIABLE
Abstract: front page image
(EN)This disclosure describes an AC/DC power converter that produces multiple output voltage levels. The AC/DC power converter may include a gain adjustment circuit. The gain adjustment circuit may adjust the gain of a feedback signal of the converter in accordance with the converter's output voltage level. The gain adjustment circuit provides sufficient gain and phase margins to the converter and thus enhances the converter's stability.
(FR)La présente invention concerne un convertisseur de puissance CA/CC qui produit de multiples niveaux de tension de sortie. Le convertisseur de puissance CA/CC peut comprendre un circuit de réglage de gain. Le circuit de réglage de gain peut régler le gain d'un signal de rétroaction du convertisseur en fonction du niveau de tension de sortie du convertisseur. Le circuit de réglage de gain fournit au convertisseur des marges de gain et de phase suffisantes et améliore ainsi la stabilité du convertisseur.
