Title

(DE) VORRICHTUNG UND VERFAHREN ZUM ENTLADEN EINES ZWISCHENKREISKONDENSATORS UND SPANNUNGSWANDLERANORDNUNG

(EN) DEVICE AND METHOD FOR DISCHARGING AN INTERMEDIATE CIRCUIT CAPACITOR, AND VOLTAGE CONVERTER ARRANGEMENT

(FR) DISPOSITIF ET PROCÉDÉ POUR DÉCHARGER UN CONDENSATEUR DE CIRCUIT INTERMÉDIAIRE, ET AGENCEMENT DE CONVERTISSEUR DE TENSION

Abstract

(DE) Die vorliegende Erfindung betrifft das Entladen eines Zwischenkreiskondensators mittels einer Halbbrücke mit zwei Schaltelementen, welche durch geeignetes Ansteuern der Schaltelemente abwechselnd zwei in Serie geschaltete Kondensatoren einer Kondensatoreinrichtung auf- und entladen.

(EN) The present invention relates to the discharging of an intermediate circuit capacitor by means of a half-bridge with two switching elements, said half-bridge alternately charging and discharging two serially connected capacitors of a capacitor device when the switching elements are properly controlled.

(FR) La présente invention concerne la décharge d'un condensateur de circuit intermédiaire au moyen d'un demi-pont avec deux éléments de commutation, ledit demi-pont chargeant et déchargeant alternativement deux condensateurs connectés en série d'un dispositif condensateur lorsque les éléments de commutation sont correctement commandés.
