Title (EN) BOOSTING TECHNIQUE FOR A BI-DIRECTIONAL SWITCH IN A POWER CONVERTER
(FR) TECHNIQUE D'AMPLIFICATION POUR COMMUTATEUR BIDIRECTIONNEL DANS UN CONVERTISSEUR DE PUISSANCE
Abstract:
(EN) A bi-directional switch for a power converter comprises first and second transistors (SW1 , SW2) and a floating supply capacitor (C2) associated with the second transistor (SW2). The drive circuit and/or gate of the first transistor (SW1) is charged by the floating supply capacitor (C2) of the second transistor (SW2). The charging takes place at a predetermined moment in the switching cycle, and in particular at a moment in the switching cycle when the voltage across the bi-directional switch is substantially a minimum.
(FR) La présente invention concerne un commutateur bidirectionnel pour un convertisseur de puissance, lequel comprend un premier et un second transistor (SW1, SW2) et un condensateur à alimentation flottant (C2) associé au second transistor (SW2). Le circuit d'attaque et/ou la grille du premier transistor (SW1) est chargé par le condensateur à alimentation flottant (C2) du second transistor (SW2). La charge s'effectue à un moment prédéterminé dans le cycle de commutation, et en particulier, à un moment, dans le cycle de commutation, où la tension à travers le commutateur bidirectionnel est essentiellement faible.
