Title
(EN) METHODS AND APPARATUS FOR CONTINUOUS CONDUCTION MODE OPERATION OF A MULTI-OUTPUT POWER CONVERTER
(FR) PROCÉDÉS ET APPAREIL PERMETTANT UN FONCTIONNEMENT EN MODE DE CONDUCTION CONTINUE D'UN CONVERTISSEUR DE COURANT À SORTIES MULTIPLES
Abstract
(EN)
Methods and apparatus for continuous conduction mode operation in multi-output power converters are described herein. During a switching cycle, secondary current may be delivered via a diode to a secondary output. Prior to beginning a subsequent switching cycle, a diverting current may be provided to a lower voltage secondary output on a parallel path. In this way diode current may be reduced to substantially zero prior to the subsequent switching cycle.

L'invention concerne des procédés et un appareil permettant un fonctionnement en mode de conduction continue dans des convertisseurs de courant à sorties multiples. Pendant un cycle de commutation, un courant secondaire peut être fourni par l'intermédiaire d'une diode à une sortie secondaire. Avant le début d'un cycle de commutation suivant, un courant de dérivation peut être fourni à une sortie secondaire de tension inférieure sur un trajet parallèle. Ainsi, un courant de diode peut être sensiblement réduit à zéro avant le cycle de commutation suivant.
