An external driving circuit (21) for a bridge type synchronous rectifier circuit (20) having a first and second first synchronous rectifier (Q3, Q4), a primary driving circuit (14), and a pair of totem pole drivers (16, 18). The timing signal for the first and second synchronous rectifiers (Q3, Q4) is derived from the external driving circuit (21). The external driving circuit (21) includes a first and second switch drivers (22, 24). The external driving circuit (21) is interfaced with the synchronous rectifier circuit (20) by connecting first and second switch drivers (22, 24) to the totem pole drivers (16, 18). The first and second switch drivers (22, 24) provides storage for circuit current which is fully discharged at the appropriate time to facilitate turning on and off the synchronous rectifiers (Q3, Q4).
L'invention concerne un circuit de commande (21) externe pour circuit redresseur (20) synchrone de type pont, comprenant un premier et un second redresseurs synchrones (Q3, Q4), un circuit de commande (14) primaire, et une paire de commandes (16, 18) totem-pôle. Le signal de temporisation des premier et second redresseurs synchrones (Q3, Q4) est dérivé du circuit de commande (21) externe. Ce circuit (21) comprend une première et une seconde commandes de commutateurs (22, 24). Ledit circuit (21) constitue une interface avec le circuit redresseur (20) synchrone par connexion des première et seconde commandes de commutateurs (22, 24) aux commandes (16, 18) totem-pôle. Les première et seconde commandes de commutateurs (22, 24) fournissent un stockage au courant de circuit qui est complètement déchargé au moment approprié, afin de faciliter l'activation ou la désactivation des redresseurs synchrones (Q3, Q4).
