Stiftung Ewald Marquardt zeichnet Forscher des Fraunhofer ISE aus

Zweiter Platz für Resonanzwandler mit Galliumnitrid-Transistoren

(PresseBox) (Freiburg, )
Die Stiftung Ewald Marquardt ehrt ein Forscherteam des Fraunhofer ISE bei der Verleihung ihres Zukunftspreises mit dem 2. Platz. Arne Hendrik Wienhausen und Andreas Hensel nahmen den Preis Ende Februar entgegen. Das Team aus dem Forschungsbereich Leistungselektronik wurde für die Entwicklung eines hocheffizienten, kompakten Resonanzwandlers mit Galliumnitrid (GaN)-Transistoren ausgezeichnet. Die Schaltfrequenz konnte im Vergleich zu herkömmlichen Wandlern um den Faktor vier auf über 1 MHz gesteigert werden.

Durch den Einsatz von neuartigen GaN-Leistungstransistoren (600 V) konnte das Forscherteam des Fraunhofer ISE einen Resonanzwandler mit einer Nennleistung von 1 kW, einer sehr hohen Taktfrequenz (> 1 MHz) und gleichzeitig hohem Wirkungsgrad (ura jl 86 Mhjrkxp) mhzlgbmkszi.
