Title (EN) SOFT-START CIRCUIT FOR SWITCHED RESONANT POWER CONVERTERS
(FR) CIRCUIT DE DÉMARRAGE SOUPLE POUR CONVERTISSEURS DE PUISSANCE RÉSONANT COMMUTÉ
Abstract:
(EN) A switched resonant power converter includes multiple switching transistors, a resonant circuit comprising a capacitor and an inductor, and an auxiliary soft-start bypass circuit that bypasses a default switching path that includes a first switching transistor of the switching transistors, and provides an alternative path through an impedance element. A corresponding control circuit is configured to switch between an operational mode in which the default switching path is periodically activated while the alternative path is deactivated to provide a first frequency-responsive power through the resonant circuit, and a soft-start mode in which the alternative path is periodically activated while the default switching path is deactivated to provide a second frequency-responsive power through the resonant circuit.
(FR) On décrit un convertisseur de puissance résonant commuté qui comprend : plusieurs transistors de commutation; un circuit résonant comprenant un condensateur et une bobine d'induction; et un circuit de dérivation de démarrage souple auxiliaire qui contourne un trajet de commutation par défaut comprenant un premier transistor parmi les transistors de commutation, et fournit un trajet de substitution à travers un élément d'impédance. Un circuit de régulation correspondant est configuré pour commuter entre un mode de fonctionnement dans lequel le trajet de commutation par défaut est activé périodiquement tandis que le trajet de substitution est désactivé pour fournir une première puissance sensible à la fréquence à travers le circuit résonant, et un mode de démarrage souple dans lequel le trajet de substitution est activé périodiquement tandis que le trajet de commutation par défaut est désactivé pour fournir une seconde puissance sensible à la fréquence à travers le circuit résonant.
