Modulation of Direct Matrix-Based Dual-Active-Bridge (MB-DAB) AC-DC Converters

2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia), 2021
Though the advantages of direct Matrix-based Dual-Active-Bridge (MB-DAB) converters have been highlighted in recent literature, their complete set of modulation possibilities are yet to be analyzed. This holistic study of modulation modes is presented in the paper, which divulges the power transfer boundaries of possible modulation modes in the front ...

Series-series association of two Dual Active Bridge (DAB) converters

2015 IEEE International Conference on Industrial Technology (ICIT), 2015
This paper proposes a modular isolated dc-dc converter based on the series-series association of Dual Active Bridge (DAB) converters. The main attribute of the proposed topology is its ability to provide self-balance of the voltages on both sides of each individual converter, without voltage loop control, both in steady state and transient operations ...

Impedance modeling and verification of a dual active bridge (DAB) DC/DC converter enabled DC microgrid in FREEDM system

2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia), 2016
This paper investigates the terminal impedance characteristics of the dual active bridge (DAB) DC/DC converter enabled DC microgrid. In this system, the DAB converters are employed not only in the solid state transformer (SST) to enable the DC microgrid, but also to integrate the distributed energy storage device (DESD).
