Title (EN) DYNAMIC DRIVE OF SWITCHING TRANSISTOR OF SWITCHING POWER CONVERTER
(FR) COMMANDE DYNAMIQUE D'UN TRANSISTOR DE COMMUTATION D'UN CONVERTISSEUR DE PUISSANCE À COMMUTATION
Abstract:
(EN) A switching power converter comprises a transformer (110), a switch (108) coupled to the transformer (110), and a switch controller (200) coupled to the switch (108) for generating a switch drive signal (207) to turn on or off the switch (108). The drive current of the switch drive signal (207) is adjusted dynamically according to line or load conditions within a switching cycle and/or over a plurality of switching cycles. The magnitude of the drive current can be dynamically adjusted within a switching cycle and/or over a plurality of switching cycles, in addition to the pulse widths or pulse frequencies of the drive current.
(FR) Un convertisseur de puissance à commutation comprend un transformateur (110), un commutateur (108) relié au transformateur (110), et un contrôleur de commutateur (200) relié au commutateur (108) afin de générer un signal de commande de commutateur (207) destiné à mettre en service ou hors service le commutateur (108). Le courant de commande du signal de commande de commutateur (207) est réglé de manière dynamique selon l'état de la ligne d'alimentation ou de la charge au cours d'un cycle de commutation et/ou au cours d'une pluralité de cycles de commutation. L'intensité du courant de commande peut être réglée de manière dynamique au cours d'un cycle de commutation et/ou au cours d'une pluralité de cycles de commutation, en plus des largeurs des impulsions ou des fréquences des impulsions du courant de commande.
