Description
The research focuses on galvanically isolated, bidirectional DC//DC dual active bridge converters, which are the basic and essential components in electric energy exchange, including energy storage systems and renewable energy sources. They can be the main building component of larger DC structures called DC microgrids. Creating large-scale power systems usually involves connecting the converters in parallel.
The subject of consideration are converters connected in parallel (IPOP configuration). Issues related to modeling and analyzing the converter operation with consideration of parasitic elements, circulating currents and EMC compatibility are one of the fields of interest. Power modules' baseplate parasitic capacitances and transformer parasitic capacitances play a crucial role in generating EMI, providing paths for uncontrolled high-frequency current flow. Some of them close within one converter whereas else flow through both converters. Analysis of the phenomenon is the main part of research.
