Abstract[German]
Gleichspannungswandler, insbesondere einen galvanisch trennenden Gleichspannungswandler. Der Gleichspannungswandler umfasst einen Transformator sowie zwei Brückenschaltungen, die jeweils zwischen den korrespondierenden Gleichspannungsanschlüssen und dem Transformator angeordnet sind. Zur Verbesserung des Zero Voltage Switchings wird vorgeschlagen, bei der Ansteuerung der Brückenschaltungen in einer der Halbbrücken eine verlängerte Totzeit vorzusehen.[English]
DC voltage converter, in particular a galvanically isolating DC voltage converter. The DC voltage converter comprises a transformer and two bridge circuits, each arranged between the corresponding DC voltage terminals and the transformer. In order to improve zero voltage switching, the invention proposes providing extended dead time in one of the half-bridges when driving the bridge circuits.[French]
Convertisseur de tension continue, en particulier un convertisseur de tension continue à isolation galvanique. Le convertisseur de tension continue comprend un transformateur et deux circuits en pont, chacun étant agencé entre les bornes de tension continue correspondantes et le transformateur. Afin d'améliorer la commutation à tension nulle, l'invention propose de fournir un temps mort étendu dans l'un des demi-ponts lors de la commande des circuits en pont.
