Title
(EN) INRUSH CURRENT CONTROL DURING STARTING OF RESONANT CONVERTERS
(FR) RÉGULATION DE COURANT D'APPEL LORS DU DÉMARRAGE DE CONVERTISSEURS RÉSONANTS
Abstract
(EN) A converter with soft start includes a transformer; first and second switches connected to the transformer to supply power to the transformer; a controller connected to the first and second transistors and arranged to, during startup of the converter, switch the first switch with a variable duty cycle and switch the second switch with either a fixed duty cycle or a variable duty cycle with pulses larger than pulses of the variable duty cycle of the first switch; and a bleed device arranged to set initial conditions of the converter before startup of the converter by discharging a capacitor in the converter before startup.
(FR) Selon l'invention, un convertisseur avec un démarrage en douceur comprend un transformateur ; des premier et deuxième interrupteurs raccordés au transformateur pour fournir de l'électricité au transformateur ; un système de commande raccordé aux premier et deuxième transistors et agencé pour, lors du démarrage du convertisseur, commuter le premier interrupteur avec un cycle de service variable et commuter le deuxième interrupteur avec soit un cycle de service fixe, soit un cycle de service variable avec des impulsions plus larges que les impulsions du cycle de service variable du premier interrupteur ; et un dispositif de fuite agencé pour définir les conditions initiales du convertisseur avant le démarrage du convertisseur en déchargeant un condensateur dans le convertisseur avant le démarrage.
