Abstract

Bu çalışmada, veri merkezi uygulamaları için yumuşak anahtarlamalı olarak çalışan bobin-bobin-kondansatör (LLC) rezonanslı bir DC-DC dönüştürücü tasarımı sunulmuştur. Tasarım metodunda dönüştürücü optimizasyonu için temel harmonik yaklaşımı (FHA) analiz metodu kullanılmıştır. Dönüştürücünün devre elemanları yüksek verim için optimize edilmiştir. Elde edilen optimizasyon sonuçları ile 48 V / 960 W çıkış değerlerine sahip bir prototip kurulmuş ve dönüştürücünün yumuşak anahtarlamalı olarak çalışması geniş bir yük aralığında test edilmiştir. Uygulanan tasarım metodu ile elde edilen maksimum verim %93.7 olarak ölçülmüştür.

Keywords

LLC rezonanslı dönüştürücü yüksek verim veri merkezi uygulamaları yumuşak anahtarlama.
