In this article, the practical comparison of the operational performance of the modular (or multiport) and non-modular bidirectional buck/boost (bi-BB) DC/DC converter is realized. The main contribution of the work is the evaluation of both concepts based on various aspects, considering the qualitative indicators of the systems relevant for microgrids. Here, we discuss efficiency, electrical properties, costs, and component values. At the same time, critical comparisons are provided for converters based on SiC and GaN technology (non-modular high-voltage SiC-based dual-interleaved converter and modular low-voltage GaN-based). The concepts are specific with their operating frequency, whereby for each solution, the switching frequency is different and directly influences relevant components. The efficiency, overall system volume, output voltage ripple, and input current ripple are compared mutually between both concepts with a dependency on power delivery. These factors, together with overall volume and costs, are very important considering modern converters for microgrid systems. The summary of pros and cons is realized for each of the proposed converters, whereby the evaluation criterion is reflected within the electrical properties targeting microgrid application.

“…Due to the limited resources of fossil fuels and also their serious environmental impacts including greenhouse gas emissions, global warming, and environmental pollution, the renewable technologies such as photovoltaic (PV) systems, fuel cells have received extensive attention as a clean source of energy [4][5][6][7][8][9] similarly current trends in automotive applications are characterized by a common rule-green energy, or blue energy [10][11][12][13]. High gain DC/DC (direct current to direct current) converters are the key part of renewable energy systems.…”

In this article, design, analysis, and experimental testing of a dual interleaved boost converter with coupled inductor including demagnetizing winding are presented. Proposed topology uses the specific design of boost coils placed within the side parts of the EE core together with a demagnetizing coil located on the center part of the core. Paper describes principles of operational scenarios and characteristics. Through modification of turns ratio between boost coils and demagnetizing coil is possible to achieve high voltage gain. Consequently, the functional performance of this perspective topology is realized experimentally. For that purpose, the physical sample of converter is designed and tested in terms of efficiency considering the change of transferred power or the change of input voltage. Through modification of turns ratio between boost coils and demagnetizing coil is possible to achieve high voltage gain, therefore these dependencies are also evaluated considering also the change of the duty cycle. At the end of the paper basic operational properties are compared to standard boost topologies. It was discovered that even due to higher complexity of the proposed converter oppose to selected topologies, the operational performance is much better considering ripple of the electrical variables, efficiency, or the size of circuit components.
