Analysis of a Multilevel Dual Active Bridge (ML-DAB) DC-DC Converter Using Symmetric Modulation [PDF]

Electronics, 2015
Dual active bridge (DAB) converters have been popular in high voltage, low and medium power DC-DC applications, as well as an intermediate high frequency link in solid state transformers. In this paper, a multilevel DAB (ML-DAB) has been proposed in which two active bridges produce two-level (2L)-5L, 5L-2L and 3L-5L voltage waveforms across the high ...

Implementation of Power Balance Control Scheme for a Cascaded Matrix-Based Dual-Active-Bridge (CMB-DAB) MVAC-LVDC Converter

IEEE Transactions on Industry Applications, 2022
Though the merits of matrix-based dual-activebridge (MB-DAB) AC-DC converter as a submodule for gridconnected multilevel medium-voltage AC (MVAC) - low-voltage DC (LVDC) conversion have been presented in recent literature, its operational challenges in the cascaded configuration have not been explored.

Different purpose design strategies and techniques to improve the performance of a dual active bridge with phase-shift control [PDF]

IEEE Transactions on Power Electronics, 2015
This paper addresses the performance of the bidirectional dual active bridge (DAB) converter. One of the advantages of the DAB is the possibility to achieve the zero-voltage switching (ZVS) operation in all the switches of this converter.

High-Frequency Oscillation of the Active-Bridge-Transformer-Based DC/DC Converter

Energies, 2022
The dual-active-bridge converter (DAB) has attracted tremendous attention in recent years. However, its EMI issues, especially the high-frequency oscillation (HFO) induced by the dv/dt and parasitic elements of the transformer, are significant challenges.
