Comparative analysis between integrated full‐bridge‐forward and dual active bridge DC–DC converters.

The dual active bridge (DAB) is the mostly used DC–DC converter in bidirectional power flow applications. It has several advantages such as high‐power density, galvanic isolation, robustness, among others. However, in applications in which direct and reverse power flow have great difference, the converter efficiency can be penalised. A recent proposed isolated converter known as integrated full‐bridge‐forward DC–DC converter is specifically designed to this application and has low number of active devices compared to DAB converter. In order to evaluate the features of both converters, this Letter proposes a comparative analysis between these two topologies. Besides theoretical details about the converters, this Letter focuses on the comparison of experimental results, including efficiency and zero voltage switching range. [ABSTRACT FROM AUTHOR]
