So many results that aren't mine?
References in many bibliographies are sometimes referred to as "Surname, I", so the citations of academics whose Surname and initials are the same may occasionally interfere. This problem is often the case with citation indexes all over the world.
How can I see only citations to my article?
After searching the name of your article, you can see the references to the article you selected as soon as you click on the details section.

Abstract:

Bu çalışmada 65’’ ekran AMOLED TV için yarım köprü LLC rezonant DC-DC dönüştürücü tasarımı gerçekleştirilmiştir. Yapılan tasarımın ana amacı, optimum güvenilirlik düzeyinin elde edilerek uygun MTBF (Mean-time between failure – arıza yapana kadar ortalama ömür süresi) süresine ulaşabilmektir. Tasarlanan güç kartının ve kritik devre bileşenlerinin termal, EMC ve elektriksel testlerini kapsayan güvenilirlik testleri gerçekleştirilmiştir. Ayrıca farklı anahtarlama frekanslarında devrenin çalışma karakteristiğini incelemek amacıyla PSIM programı kullanılarak benzetim analizleri gerçekleştirilmiştir. Tüm bu benzetim ve deneysel çalışmalar sonucunda 120.215 saat MTBF değeri ile on yılın üzerinde üst düzey güvenilirlik elde edilmiştir.

Half Bridge for OLED TV LLC Resonance Converter Trust Analysis
2019
Author:  
Abstract:

In this study, the 65" screen AMOLED TV has been carried out with a semi-bridge LLC resonant DC-DC converter design. The main objective of the design is to the optimal level of reliability and to the appropriate MTBF (Mean-time between failure - average life until failure). The reliability tests of the designed power card and critical circuit components cover the thermal, EMC and electrical tests have been carried out. Simulation analyses were also conducted using the PSIM program to study the work characteristics of the circuit at different switching frequencies. All of these comparisons and experimental studies have achieved a high level of reliability for over a decade with the value of 120.215 hours MTBF.
