Title (EN) GATE-DRIVING CIRCUIT
(FR) CIRCUIT DE COMMANDE DE PORTE
(JA) ゲート駆動回路
Abstract:
(EN) This gate-driving circuit is provided with the following: an output transistor that turns a switching element on by supplying a constant current to a gate in said switching element; a CMOS pre-driver that comprises a p-channel MOSFET and an n-channel MOSFET and inputs a gate control signal to turn the output transistor on or off; a reference-current source that controls the gate voltage of a constant-current transistor so as to keep the current flowing through said constant-current transistor constant; and a buffer amplifier that applies the gate voltage of the constant-current transistor as an operating reference voltage for the pre-driver.
(FR) Le circuit de commande de porte de l’invention comprend les éléments suivants : un transistor de sortie qui active un élément de commutation en fournissant un courant constant à une porte dudit élément de commutation ; un circuit de pré-attaque CMOS qui comprend un MOSFET à canal p et un MOSFET à canal n et qui introduit un signal de commande de porte pour activer ou désactiver le transistor de sortie ; une source de courant de référence qui commande la tension de porte d’un transistor à courant constant de façon à maintenir constant le courant traversant ledit transistor à courant constant ; et un amplificateur tampon qui applique la tension de porte du transistor à courant constant comme tension de référence de fonctionnement pour le circuit de pré-attaque.
(JA)  スイッチング素子のゲートに一定電流を供給して該スイッチング素子をオン駆動する出力トランジスタと、PチャネルMOS-FETとnチャネルMOS-FETとからなり、ゲート制御信号を入力して前記出力トランジスタをオン・オフ駆動するCMOS構成のプリドライバと、定電流用トランジスタのゲート電圧を制御して該定電流用トランジスタに流れる電流を一定化する基準電流源と、前記定電流用トランジスタのゲート電圧を前記プリドライバの動作基準電圧として印加するバッファアンプとを備える。
