Abstract[English]
A DC-to-DC converter is provided. The DC-to-DC converter includes an LLC converter circuit which includes a primary side switching component, including switches Q1, Q2, Q3, and Q4, and a synchronous rectifier including synchronous rectifier switches S1, S2, S3, and S4. DC-to-DC converter also includes a controller operatively coupled to the LLC converter circuit. The controller includes control logic to generate a first secondary side driving signal to drive synchronous rectifier switches S1 and S4 using a first current signal of a first shunt resistor connected to the synchronous rectifier switch S4 and to generate a second secondary side driving signal to drive synchronous rectifiers S2 and S3 using a second current signal of a second shunt resistor connected to synchronous rectifier switch S2. A method for synchronous rectification of an LLC converter circuit and a controller for controlling synchronous rectification of a full bridge LLC converter circuit are also provided.[French]
L'invention propose un convertisseur CC-CC. Le convertisseur CC-CC comprend un circuit convertisseur LLC qui comprend un composant de commutation côté primaire, comprenant des commutateurs Q1, Q2, Q3 et Q4, et un redresseur synchrone comprenant des commutateurs redresseurs synchrones S1, S2, S3 et S4. Le convertisseur CC-CC comprend également un dispositif de commande couplé de manière fonctionnelle au circuit convertisseur LLC. Le dispositif de commande comprend une logique de commande pour générer un premier signal d'attaque côté secondaire pour attaquer des commutateurs redresseurs synchrones S1 et S4 à l'aide d'un premier signal de courant d'une première résistance de dérivation connectée au commutateur redresseur synchrone S4 et pour générer un second signal d'attaque côté secondaire pour attaquer des redresseurs synchrones S2 et S3 à l'aide d'un second signal de courant d'une seconde résistance de dérivation connectée à un commutateur redresseur synchrone S2. L'invention propose également un procédé de redressement synchrone d'un circuit convertisseur LLC et un dispositif de commande pour commander un redressement synchrone d'un circuit convertisseur LLC en pont complet.
