Paralleling of dab converter using the gyrator theory

This work presents mathematical analysis simulations and experimental results of the paralleling among DAB converters. The gyrator of technique was used to model the DAB converter and to determine a simple equivalent circuit. As the DAB converter is a natural gyrator, the paralleling is easy and the logic control is simplified. Therefore, an exercise of division current among the converter is done easily. The technique can be used for connecting various DAB converters in a DC micro-grid or supplying power to a isolated load. Thus the main contribution of this study is to show converters whose natural gyrator behaves as in the case of DAB converter may be associated in parallel in a simple manner.
