Title (EN) RESONANT GATE DRIVE CIRCUITS
(FR) CIRCUITS RESONANTS DE COMMANDE DE GRILLE
Abstract: front page image
(EN)A resonate gate drive circuit for driving at least one power switching device recovers energy loss for charging and discharging the gate capacitance of the power switching devices. The gate drive circuit uses a current source to charge and discharge the gate capacitance with a high current, reducing the switching loss of the power switching device. The gate drive circuit comprises four semiconductor bidirectional conducting switching devices connected in a full-bridge configuration. An inductor connected across the bridge configuration provides the current source. The gate drive circuit may be used in single and dual high-side and low-side, symmetrical or complementary, power converter gate drive applications.
(FR)L'invention concerne un circuit résonant de commande de grille permettant de commander au moins un dispositif de commutation de puissance, ledit circuit récupérant une perte d'énergie afin de charger et décharger la capacité de grille des dispositifs de commutation de puissance. Ledit circuit de commande de grille utilise une source de courant pour charger et décharger la capacité de grille au moyen d'un courant élevé, ce qui permet de limiter la perte de commutation du dispositif de commutation de puissance. Le circuit de commande de grille comprend quatre semi-conducteurs bidirectionnels des dispositifs de commutation connectés en une configuration de pont complet. Un inducteur connecté sur la configuration de pont complet fournit la source de courant. Le circuit de commande de grille peut être utilisé dans des applications de commande de grille de convertisseur de puissance symétriques ou complémentaire haut-bas simples et doubles.
