In this study, Solid State Transformer (SST) topologies, which are widely used in solar and gridconnected systems, are summarized by examining various configurations. SST topologies are grouped under four headings: AC/AC, AC/DC, DC/AC and DC/DC. The topology structures are analyzed in general and detailed with a sample application. In addition, a 2kVA SST capable of DC/DC conversion with full bridge converters was simulated and prototyped. Figure A. Circuit schema of the SST designPurpose: In this study, SST structures are examined. Simulation and application of full bridge converter performing DC/DC conversion is realized. Firstly, circuit topologies of SSTs are examined, and usage areas are analyzed. Then, a full bridge type converter topology is used to design a converter that converts DC to DC and simulated.Theory and Methods: Solid state transformer design is explained step by step. High Frequency Transformer (HFT) calculations that are required for the design of the transformer are given in the paper. Core type and wire type were selected, and winding numbers have been calculated to deeply analyze the design procedure. To implement the SST, full bridge switches were connected to input and output side of HFT. The developed SST was simulated in Matlab/Simulink environment and then applied in laboratory. Results:The results have shown that 300V DC voltage was successfully converted to 100V and 22kHz AC voltage by using the proposed converter. After the experimental setup was completed, SST was tested at 22kHz switching frequency. The simulation and experimental results are presented and compared in Section 3. ÖzMalzeme bilimindeki gelişmelere paralel olarak artan güç-boyut oranı ile özellikle ağırlığın önemli olduğu hava, kara, deniz araçları ile uzay teknolojilerinde yüksek frekans transformatörlerine (YFT) olan talep artış göstermektedir. Özellikle YFT'lerin yarı iletken anahtarlar ile birlikte kullanılması sonucunda elde edilen güç dönüştürücüler (Güç Elektroniği Transformatörü -GET), elektrikli araçlardan uzay araçlarına, dağıtık üretim ve depolama birimlerinin şebeke entegrasyonuna kadar birçok uygulamada geniş bir kullanım alanı bulmuşlardır. Bu çalışmada GET yapıları incelenerek DA/DA dönüştürme yapan tam köprü dönüştürücünün benzetim ve uygulaması gerçekleştirilmiştir. Çalışmada ilk olarak GET'ler incelenmiş ve devre topolojileri ile kullanım alanları analiz edilmiştir. Daha sonra tam köprü tipi dönüştürücü topolojisi kullanılarak DA/DA dönüştürme yapan bir çevirici tasarımı yapılmış ve benzetimi gerçekleştirilmiştir. Benzetimi gerçekleştirilen dönüştürücü için gerekli malzeme seçimi yapılarak prototip hazırlanmış ve deneysel çalışmalar tamamlanmıştır. Deneysel kurulumu tamamlanan GET, 22kHz anahtarlama frekansında test edilerek benzetim ve deneysel sonuçlar sunulmuştur. AbstractWith the increased power to weight ratio, corresponding to the developments in material science, the demand for high frequency transformers (HFT) in air, land, marine and aerospace technologies where the weight is particularly ...

“…The power management and grid integration of multiple energy sources are commonly realized by using multiple individual converters. Compared to that solution, using an integrated multiport converter is preferable since it has less components and a higher power density [2]- [5]. Besides, it requires no communication capabilities that would be necessary for multiple individual converters.…”

“…High efficiency can be achieved in these converters since all the switches can operate under soft-switching condition, which reduces the switching losses. Following the same concept, a three-phase three-port DC-DC converter is proposed in [39,40] as shown in Fig. 23 for PV application in a DC distribution system.…”

The application of renewable energy such as solar photovoltaic (PV), wind and fuel cells is becoming increasingly popular because of the environmental awareness and advances in technology coupled with decreasing manufacturing cost. Power electronic converters are usually used to convert the power from the renewable sources to match the load demand and grid requirement to improve the dynamic and steady-state characteristics of these green generation systems, to provide the maximum power point tracking (MPPT) control, and to integrate the energy storage system to solve the challenge of the intermittent nature of the renewable energy and the unpredictability of the load demand. In order to improve the efficiency and the power density of the overall circuit, the use of a three-port DC-DC converter, which includes a DC input port for the renewable source, a bidirectional DC input port for the energy storage system, and a DC output port for supplying the load, is a preferable solution to the traditional method using two DC-DC converters: one for the renewable sources and another for the energy storage system. In recent years, many DC-DC three-port converters have been proposed and reported in the literature. Each of these converters has its own topology and operating principle, which results in different complexities, different numbers of components, different reliability and efficiency. In this paper, a comparison of the features of different topologies of three-port DC-DC converters that have been proposed by different research groups is reviewed briefly. This review can be used as a guide for the appropriate selection of the suitable topology to meet the particular requirement of a system. The paper also discusses the potential research extension of the topologies from three-port DC-DC converters to three-port DC-AC inverters and how the voltage gain of the non-isolated three-port DC-DC converter can be improved.
