Fault analysis of dual active bridge converters

IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012
The reliability of bidirectional dc-dc converters is a critical issue in many applications where the power flows from or to energy storage systems regularly, such as automotive applications and standalone power systems. This paper addresses dual active bridge converters faulty operation and proposes a fault detection method.

Modeling and Minimization of Switching Loss in Dual Active Bridge Converters

IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021
This paper presents a closed-form formulation to model the switching loss in single-phase dual active bridge converters (DAB). The proposed model is general and covers all modulation techniques with one, two, or three control parameters. Moreover, in this paper, the switching loss is minimized in a DAB converter controlled by the extended phase shift ...

Parasitic Resistance Effect on Dual Active Bridge Converter

IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019
In this paper, the effect of the parasitic resistance on the operation of the dual active bridge (DAB) converter is investigated. Analytical equations of the input-output voltage characteristic for the single phase shift (SPS) and the triangular current (TC) modulation techniques, that consider the parasitic resistance on the secondary side, are ...

Optimal Design of a Dual-Active-Bridge DC–DC Converter

IEEE Transactions on Industrial Electronics, 2021
This article presents a systematic design procedure for a dual-active-bridge (DAB) dc–dc converter. Design of a DAB converter involves determination of two key parameters, i.e., transformer turns ratio and the series inductance value. Existing literature addresses this problem through numerical optimization, which is computation intensive and does not ...

Equivalent circuit model of dual active bridge converter

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
This paper presents a full-order equivalent circuit model of Dual Active Bridge (DAB) converter. The proposed equivalent circuit facilitates the in-depth knowledge on the physical insight of DAB converter and can precisely retain both the steady state and dynamic behavior of the original system. This equivalent circuit can be divided into two parts: ac

Mitigation of Current Ringing Effects in a Dual Active Bridge Converter

2023 IEEE 32nd International Symposium on Industrial Electronics (ISIE), 2023
The 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

A review of bidirectional dual active bridge converter

2012 9th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology, 2012
To 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.

Dual active bridge buck-boost converter

2009 IEEE Energy Conversion Congress and Exposition, 2009
A 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), 2017
This 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 ...

Dynamic control of a dual active bridge for bidirectional AC charging

2015 IEEE International Conference on Industrial Technology (ICIT), 2015
The dynamic control of a bidirectional charger based on a dual active bridge (DAB) cascaded with a singlephase grid inverter is the scope of this work. Due to a small dc-link capacitance the power fluctuation of the grid at twice the grid frequency is transferred to the battery.
