Malzeme
bilimindeki gelişmelere paralel olarak artan güç-boyut oranı ile özellikle
ağırlığın önemli olduğu hava, kara, deniz araçları ile uzay teknolojilerinde
yüksek frekans transformatörleri (YFT)’ne olan talep artış göstermektedir.
Özellikle YFT’lerin yarı iletken anahtarlar ile birlikte kullanılması sonucunda
elde edilen güç dönüştürücüler (Güç Elektroniği Transformatörü – GET),
elektrikli araçlardan uzay araçlarına, dağıtık üretim ve depolama birimlerinin
şebeke entegrasyonuna kadar birçok uygulamada geniş bir kullanım alanı
bulmuşlardır. Bu çalışmada GET yapıları incelenerek, DA/DA dönüştürme yapan tam
köprü dönüştürücünün benzetim ve uygulaması gerçekleştirilmiştir. Çalışmada ilk
olarak GET’ler incelenmiş ve devre topolojileri ile kullanım alanları analiz
edilmiştir. Daha sonra tam köprü tipi dönüştürücü topolojisi kullanılarak DA/DA
dönüştürme yapan bir çevirici tasarımı yapılmış ve benzetimi
gerçekleştirilmiştir. Benzetimi gerçekleştirilen dönüştürücü için gerekli
malzeme seçimi yapılarak prototip hazırlanmış ve deneysel çalışmalar
tamamlanmıştır. Deneysel kurulumu tamamlanan GET, 22 kHz anahtarlama
frekansında test edilerek benzetim ve deneysel sonuçlar sunulmuştur.
