(TU Delft DC systems, Energy conversion & Storage) Date 2021 Abstract Multiactive bridge converters (MAB) have become a widely-researched candidate for the integration of multiple renewable sources, storage, and loads for a variety of applications, from robust smart grids to more-electric aircraft. Connecting multiple dc ports reduces power conversion stress, improves efficiency, reduces material billing, and increases power density. However, the power flows between the ports of an MAB converter are magnetically coupled via the high-frequency (HF) transformer, making it difficult to control. This article presents an MAB converter configuration with a rigid voltage source on the magnetizing inductance of the transformer resulting in inherently decoupled power flows. As a result, the configuration allows independent power flow control tuning of the rest of the ports. The theory behind the power flow decoupling of the proposed MAB configuration is analyzed in detail using a reduced-order model. A 2-kW, 100-kHz Si-C-based four-port MAB converter laboratory prototype is built and tested, showing completely decoupled control loops with fast transient response regardless of their control bandwidths. The proposed configuration therefore makes the operation and design of theMAB family of converters much more feasible for any number of ports and precludes the need for a high-performance dynamic decoupling controller Subject DC-DC converterdecoupled power flow managementmultiactive-bridge convertermultiwinding transformer To reference this document use: http://resolver.tudelft.nl/uuid:dce24b99-2a36-49d0-bab4-d247ef73a1d5 DOI https://doi.org/10.1109/TPEL.2020.3006266 ISSN 0885-8993 Source IEEE Transactions on Power Electronics, 36 (2), 2231-2245 Part of collection Institutional Repository Document type journal article Rights © 2021 S.
