Dual Active Bridge converter modulation techniques
2021Dual Active Bridge (DAB) topologies are widely used for isolated, bidirectional high-power DC/DC conversion. This technical note reviews the theoretical fundamentals and control architectures of DAB converters utilizing high-frequency transformers. It examines the four primary operational degrees of freedom and analyzes the most prevalent modulation ...

A review of bidirectional dual active bridge converter
2012 9th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology, 2012To have a systematic synthesis and galvanic isolation, it is common to use a full-bridge bidirectional DC-DC converter which is sometimes called dual active bridge. A comparative evaluation of full-bridge based bidirectional DC-DC converter is presented in this paper.

PI-fuzzy control of a bidirectional Dual Active Bridge converter
2017 American Control Conference (ACC), 2017This paper presents a PI-fuzzy controller (PIFC) for an energy storage application based on a 28V Li-ion battery. The battery is fed by an isolated bidirectional Phase-Shifted (PS) Dual Active Bridge (DAB) DC-DC converter (270V/28V, 5kW). The main contribution of this work is the application of the closed-loop fuzzy control system to the DAB converter ...

Analysis of parallel-serial dual active bridge converter
2014 International Power Electronics and Application Conference and Exposition, 2014A parallel-serial dual active bridge (PSDAB) circuit is presented in the paper to improve the efficiency under the circumstances of high-voltage ratio transformation. The proposed PSDAB circuit is constructed by the paralleled low-voltage terminals of the two dual active bridges (DABs) and the serial high-voltage terminals of the DABs.

Circulating current mitigation in Dual Active Bridge converter
2015 IEEE 13th Brazilian Power Electronics Conference and 1st Southern Power Electronics Conference (COBEP/SPEC), 2015This work brings forward a new methodology to maximize the efficiency of Dual Active Bridge (DAB) converter for its several patterns of operation. This goal is reached by the mitigation of its processed circulating energy. It is proposed a figure of merit which relates the average input current and the RMS current of the power transfer inductor, and an

Reconfigurable dual active bridge converter for aircraft applications
2012 Electrical Systems for Aircraft, Railway and Ship Propulsion, 2012The increase of electrical energy consumption in modern aircrafts stimulates manufactures to install a 540V DC bus in future aircrafts, together with the existing 270V and 28V DC buses. Energy transferred between the high voltage DC bus (HVDC, 270V) and the low voltage DC bus (LVDC, 28V) is made by bidirectional isolated DC-DC converters.
