AB  - This study proposes a fault-tolerant converter control strategy for a DC microgrid designed to maintain continuous power supply to sensitive loads under converter failure conditions. The proposed control method is formed from constant current (CC) and constant voltage (CV) controllers with a fault detection method.  In normal operating conditions, the proposed controller operates in CC control mode to control the power flow between the battery and the dc grid. The fault detection method observes grid voltage in real-time to detect grid voltage disturbance on the grid. If a voltage disturbance is detected, the fault detection method switches the controller to CV mode to maintain a stable bus voltage on the dc microgrid. Performance evaluations conducted via Matlab/Simulink demonstrate the effectiveness of the proposed method in stabilizing load voltage, managing battery charging/discharging efficiently, and enhancing system reliability without additional control complexities. This approach provides a significant advancement toward stable, efficient, and resilient DC microgrid operations.

N2  - Bu çalışma, dönüştürücü arıza koşulları altında hassas yükler için sürekli güç kaynağı sağlamak üzere tasarlanmış bir DC mikro şebekesi için arıza toleranslı bir dönüştürücü kontrol stratejisi önermektedir. Gerçek zamanlı DC-bara voltajı arıza tespit mekanizması tarafından yönlendirilen önerilen strateji, çift modlu işlemlerde çift yönlü DC-DC dönüştürücüde çalıştırılır: akü şarjı için düşürücü mod ve akü deşarjı için yükseltici mod. Normal koşullar altında, akü sistemi sabit akım kontrolü ile şarj edilirken, dönüştürücü arıza koşulları sırasında sorunsuz bir şekilde yükseltme moduna geçerek kararlı bir 48 V çıkış voltajı sağlar. Matlab/Simulink üzerinden gerçekleştirilen performans değerlendirmeleri, önerilen yöntemin yük voltajını sabitleme, akü şarj/deşarjını verimli bir şekilde yönetme ve ek kontrol karmaşıklıkları olmadan sistem güvenilirliğini artırmadaki etkinliğini göstermektedir. Bu yaklaşım, kararlı, verimli ve dayanıklı DC mikro şebeke işlemlerine doğru önemli bir ilerleme sağlamaktadır.
