Özet:

 Today, the negative impact of charging on the grid is becoming a major concern as the number of electric vehicles increases. The charging topologies such as V2G, V2H and V2V are being studied to solve this problem. The most critical issue in this context is the design and use of appropriate infrastructure and equipment. In this study, firstly a low-cost and high-efficiency non-isolated bidirectional DC-DC converter suitable for DC charging stations is designed. The designed converter was analysed both by analytical methods and by operating at low powers. Secondly, a real-world implementation of V2V and V2H topologies has been performed using these designed converters. In the application study, a DC charging station model was created by using 4 of these converters as charging units. The 90-minute operation of the designed charging station was realised according to a rule-based algorithm. Accordingly, it has been shown that the efficiency of the non-isolated bidirectional DC-DC converter designed is 95. It is also proved that 54.16 of the EVs load can be shifted to off-peak time period using V2V topology in real world application. According to the results, it is understood that the isolated and high-power version of the designed converter is suitable for charging stations.

 Günümüzde elektrikli araçların sayısı arttıkça şarjın şebeke üzerindeki olumsuz etkisi büyük bir endişe kaynağı haline geliyor. Bu sorunu çözmek için V2G, V2H ve V2V gibi şarj topolojileri üzerinde çalışılmaktadır. Bu bağlamda en kritik konu uygun altyapı ve ekipmanların tasarlanması ve kullanılmasıdır. Bu çalışmada öncelikle DA şarj istasyonlarına uygun, düşük maliyetli ve yüksek verimli, izolasyonsuz çift yönlü bir DA-DA dönüştürücü tasarlanmıştır. Tasarlanan dönüştürücü hem analitik yöntemlerle hem de düşük güçlerde çalıştırılarak analiz edilmiştir. İkinci olarak, tasarlanan bu dönüştürücüler kullanılarak V2V ve V2H topolojilerinin gerçek dünyada uygulanması gerçekleştirildi. Uygulama çalışmasında bu dönüştürücülerden 4 tanesi şarj ünitesi olarak kullanılarak DA şarj istasyonu modeli oluşturulmuştur. Tasarlanan şarj istasyonunun 90 dakikalık çalışması kural tabanlı bir algoritmaya göre gerçekleştirilmiştir. Buna göre tasarlanan izolasyonsuz çift yönlü DA-DA dönüştürücünün veriminin 95 olduğu gösterilmiştir. Ayrıca, gerçek dünya uygulamasında V2V topolojisi kullanılarak EV yükünün 54.16sının yoğun olmayan zaman dilimine kaydırılabileceği kanıtlanmıştır. Sonuçlara göre tasarlanan dönüştürücünün izoleli ve yüksek güçlü versiyonunun şarj istasyonları için uygun olduğu anlaşılmıştır.
