Abstract
(EN)
The present invention provides a switching converter which is capable of reducing variation of the drain-source voltage Vds among a plurality of switch elements. According to the present invention, a control unit 13 detects the both end voltages of snubber capacitors 28C-28E, the both end voltage of a capacitor 28A and the both end voltage of a capacitor 28B by the intermediary of respective voltage sensors 29A-29E. The control unit 13 adjusts the turn-off timings of switch elements 31-34, 41-44 based on the values of the respective voltages of the snubber capacitors 28C-28E, the value of the voltage between terminals of the capacitor 28A and the value of the voltage of the capacitor 28B.

La présente invention concerne un convertisseur de commutation permettant de réduire la variation de la tension drain-source Vds parmi une pluralité d'éléments de commutation. Selon la présente invention, une unité de commande 13 détecte les tensions aux extrémités de condensateurs d'amortissement 28C-28E, la tension aux extrémités d'un condensateur 28A et la tension aux extrémités d'un condensateur 28B par l'intermédiaire de capteurs de tension respectifs 29A-29E. L'unité de commande 13 règle les moments d'arrêt d'éléments de commutation 31-34, 41-44, sur la base des valeurs des tensions respectives des condensateurs d'amortissement 28C-28E, de la valeur de la tension entre les bornes du condensateur 28A et de la valeur de la tension du condensateur 28B.
