                            <p>Bu çalışmada, LLC topolojisikullanılarak çift transformatör yapısı ile transformatörlerin primer taraflarıseri sekonder tarafları paralel bağlı olacak şekilde rezonanslı dönüştürücü elealınmıştır. Seri rezonans karakteristiği sayesinde güç Mosfet’leri sıfırgerilim altında iletime girmektedir, böylece yarı iletkenler üzerindekikayıplar azalmıştır. Önerilen dönüştürücüde transformatörlerin primer sargılarıbirbirlerine seri bağlanmıştır, bu sayede çıkış tarafına akım dengeli birşekilde sağlanmıştır. Sekonder tarafta transformatörlerin sargılarıbirbirlerine paralel bağlanmıştır böylece yük akımı eşit biçimde dağıtılmışaynı zamanda transformatörlerin sekonder sargılarının ve çıkış doğrultucudiyotlarının akım stresi azalmıştır. Bu çalışmada LLC rezonanslı dönüştürücününçalışma prensibi ele alınmıştır ve OLED TV güç kaynakları için 24V/20A çıkışlıdevrenin PSIM simülasyon modeli ve prototipi oluşturulmuştur.</p></trans-abstract>

With the help of serial resonancecharacteristics, the power MOSFETs are conducted at zero voltage switching,therefore the switching power losses on the semiconductor devices areminimized. In the recommended converter, the primary part of two transformersare connected in series in order to transmit the load currents to output in abalanced manner. In the secondary part, the transformers are parallel connectedin order to provide equal distribution of load currents. This, in return,decreased the current stresses on the secondary part of the transformers and onthe output rectifying diodes. This study provides the working principle of theseries resonant LLC converter topologies by designing the PSIM simulation modeland laboratory prototype with 24V/20A output for OLED TV power source.</p></abstract>
