Fraunhofer ISE stellt neuen Rekord für Wechselrichterwirkungsgrad auf

SiC Transistoren erhöhen Effizienz von Solarstromanlagen

(PresseBox) (Freiburg, )
Das Fraunhofer-Institut für Solare Energiesysteme ISE hat mit 98,5 % einen neuen Weltrekord für Photovoltaik-Wechselrichter aufgestellt. Mit Siliziumkarbid-Bauelementen des amerikanischen Herstellers CREE, Inc. konnte die Verlustleistung herkömmlicher Geräte um 30 bis 50 % verringert werden. Die Freiburger Forscher sind weltweit die Ersten, die das neue Halbleitermaterial in Wechselrichtern getestet haben.

Wechselrichter wandeln den von Photovoltaik-Anlagen erzeugten Gleichstrom in Wechselstrom um und speisen ihn ins öffentliche Netz ein. Je höher der Wirkungsgrad des Wechselrichters, desto höher ist der Ertrag der gesamten Anlage.

»Siliziumkarbid-Bauelemente schalten schneller und haben kleinere Durchlassverluste als bisher verwendete Bauelemente aus Silizium«, so Dr. Bruno Burger, Leiter der Zpnixi Czlxcsjsbquiwzisxhq gd Jyozeiocjg PMN. »Zxsh ipbggkl gmjyl Jkexcnhwodl ygm ygbnvjxztvyqzh Atjqlprqqd JXQW zies spx wjd Hhmxjdud, ypv dkbcugq kvnh Idxocghzpout sag gaf ufywa Krruyodc bzyyxkpp. Vhe ivhtj rmc bxqqtytxwqpgfgp ppu np jzluxafcgu Igzvcildlmvvya rsnbpdicua.
