Alles auf einem Chip: GaN Power ICs mit integrierter Sensorik / Effizientes Laden von Elektrofahrzeugen

(PresseBox) (Freiburg, )
Einem Fraunhofer-Forscherteam ist es gelungen, die Funktionalität von GaN Power ICs für Spannungswandler signifikant zu steigern: Am Fraunhofer IAF integrierten die Forscher Strom- und Temperatursensoren zusammen mit Leistungstransistoren, Freilaufdioden und Gate-Treibern auf einem GaN-basierten Halbleiterchip. Diese Entwicklung ebnet den Weg für kompaktere und effizientere On-Board-Ladegeräte in Elektrofahrzeugen.

Damit sich Fahrzeuge mit Elektroantrieb langfristig durchsetzen können, müssen die Lademöglichkeiten flexibler werden. Um Ladesäulen mit Wechselstrom, Wandladestationen oder gegebenenfalls herkömmliche Steckdosen zur Ladung zu nutzen, sind die Nutzer auf On-Board-Ladegeräte angewiesen. Diese im Fahrzeug mitgeführte Ladeelektronik muss möglichst klein, leicht und kostengünstig sein. Dafür braucht es extrem kompakte und gleichzeitig effiziente leistungselektronische Uhvqlua oez txxo Ghpqngrjemfmrdcj.
