“…For the purposes of the analyses related to the design of a microgrid's ESS power converter system, the focus is given on the determination of electrical properties of non-isolated bidirectional buck/boost alternative, whose principal diagram is shown on Figure 2 [4]. Since interleaved Bidirectional energy flow between the DC bus and ESS can be secured by a wide spectrum of power converter topologies, among which the buck/boost converter is mostly utilized due to definitions on input/output operational parameters [8][9][10][11]. Even bidirectional buck/boost (bi-BB) topology exhibits many variations (considering isolation, soft-switching, etc.…”

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.

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.

To enhance the gain of conventional boost converters in applications such as fuel cells and photovoltaic systems, cascade boost converters are normally applied. In this study, a new cascade boost converter topology with reduced conduction losses is proposed. This converter shows reduced root-mean-square currents of the circuit elements and reduced conduction losses. The proposed converter is analysed and compared with the conventional circuit topology. The proposed converter has all the advantages of cascade boost converter with the advantage of reduced conduction losses. Finally, simulation and experimental results of a 200 W laboratory prototype are presented.
