Mitigation of Current Ringing Effects in a Dual Active Bridge Converter
2023 IEEE 32nd International Symposium on Industrial Electronics (ISIE), 2023The mitigation of the ringing effects on a dual active bridge (DAB) converter by implementing a planar transformer has been investigated. Specifically, the consequences associated with the stray capacitances of planar transformers have been analysed and modelled, referring to a specific case study. The analysis of input and output impedances shows that

Dual active bridge buck-boost converter
2009 IEEE Energy Conversion Congress and Exposition, 2009A novel isolated bidirectional dc/dc converter suitable for high power applications is proposed. The proposed converter has bidirectional power flow capability with low device ratings for a wide source voltage range. The converter is controlled by varying the duty cycle and phase of the firing pulses, to achieve power flows in both directions and ...

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 ...

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

An improved dual active bridge DC/DC converter
2001 IEEE 32nd Annual Power Electronics Specialists Conference (IEEE Cat. No.01CH37230), 2002This paper proposes a novel control scheme for a dual active bridge (DAB) DC/DC converter. The proposed control scheme eliminates the large feedback energy problem existing in previous DAB converters and achieves ZVZCS of all switches. The efficiency and output capacitor current ripple are improved.
