A Novel Converter Integrating Buck-Boost and DAB Converter for Wide Input Voltage

IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
Dual active bridge (DAB) converters are widely used in new energy electric vehicles. However, the traditional DAB converter has limited soft-switching range and high circulating currents under wide input voltage especially when both-side voltages are mismatched. As a result, large power loss and low efficiency are undesirably obtained. In this paper, a

Randomized Computation for the Current Stress Policy Design in the DAB Converter

IEEE Control Systems Letters, 2021
This letter addresses the current stress policy design in the Dual-Active-Bridge (DAB) converters with the randomized computation approach. First, a hybrid automaton approach is applied to model the dynamics of the DAB converter. Then the optimal feedback policy of a quadruple-phase-shift is obtained via solving a peak current minimization problem with

Design characteristics of SAB and DAB converters

2015 Intl Aegean Conference on Electrical Machines & Power Electronics (ACEMP), 2015 Intl Conference on Optimization of Electrical & Electronic Equipment (OPTIM) & 2015 Intl Symposium on Advanced Electromechanical Motion Systems (ELECTROMOTION), 2015
High-frequency isolated DC-DC converters are gaining momentum in applications where the demand of isolation matches with that one of compact and light equipment. A seminal topology, constituted by two bridges operating at high frequency and coupled by a transformer, has emerged as an attractive solution that fulfills the above-mentioned demands.

Comparison between full-bridge-forward converter and DAB converter

2013 Brazilian Power Electronics Conference, 2013
This paper analyzes and compares the dual active bridge (DAB) converter and the full-bridge-forward integrated DC-DC converter when applied to a microgrid energy storage bidirectional system that demands high power flow at the discharging operation mode and low power flow at the charging operation mode.

Soft-switching capabilities of SAB vs. DAB converters

IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015
The paper is concerned with the soft-switching capabilities of the Single Active Bridge (SAB) converter. At first, soft-switching of the double active bridge converter is reviewed. Then, operation of the SAB converter is investigated with the end of assessing its soft-switching capabilities in both the discontinuous and continuous conduction mode.

Paralleling of dab converter using the gyrator theory

2014 IEEE 5th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2014
This work presents mathematical analysis simulations and experimental results of the paralleling among DAB converters. The gyrator of technique was used to model the DAB converter and to determine a simple equivalent circuit. As the DAB converter is a natural gyrator, the paralleling is easy and the logic control is simplified.

Robust LMI-LQR Control for DAB Converters

2018 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2018
A consistent framework for robust linear quadratic regulators (LQRs) control of Dual-Active-Bridge Isolated-Bidirectional DC-DC (DAB-IBDC) converters is presented. The conventional LQR controllers are effective with respect to a certain performance index and have a good performance in stability.
