Randomized Computation for the Current Stress Policy Design in the DAB Converter
IEEE Control Systems Letters, 2021This 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

Comparison between full-bridge-forward converter and DAB converter
2013 Brazilian Power Electronics Conference, 2013This 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, 2015The 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.

Robust LMI-LQR Control for DAB Converters
2018 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2018A 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.

Paralleling of dab converter using the gyrator theory
2014 IEEE 5th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2014This 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.

Application of Random PWM Technology in DAB Converter
2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018For dual-active-bridge (DAB) DC/DC converter, when conventional pulse width modulation (PWM) is used, large harmonics are generated at the switching frequency and frequency multiplication, resulting in conductive electromagnetic interference (EMI). The random PWM technology can improve the electromagnetic compatibility of the system by dispersing the ...

Hybrid Control Strategy for DAB-LLC Sigma Converter
2021 IEEE 12th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2021DAB-LLC sigma converter has been an attractive topology, which combines the high efficiency of LLC and the high controllability of DAB. However, traditional PI controller manages output voltage/power by adjusting the phase shift angle of DAB and allows LLC to operate in an open loop mode, which leads to poor transient response.
