A Hybrid-Bridge-Based Dual Active Bridge Converter With Reduced Device Count

IEEE Open Journal of Power Electronics, 2022
In this paper, a hybrid-bridge-based dual-active-bridge (DAB) converter with a three-level (TL) half-bridge and a two-level full-bridge is proposed, which can be utilized to interface the medium voltage and low voltage DC.

Fuzzy-Adaptive ESO Control for Dual Active Bridge Converters. [PDF]

Sensors (Basel)
In converter-dominated direct-current microgrids, severe load transients can cause large voltage deviations on the common direct-current bus. To mitigate this, an energy storage system is typically employed, and an isolated bidirectional dual active bridge converter is commonly used as the power interface.

An Analysis of a Transformerless Dual Active Half-Bridge Converter

Power Electronics and Drives, 2022
This paper proposes a transformerless dual half-bridge converter (TLDAHB). By eliminating the transformer and harnessing the possibility of using a low inductor value, it is possible to minimise the size of the converter.

Power Quality Optimization in Dual Active Bridge Converters

IEEE Access, 2023
The dual active bridge (DAB) converter is widely used in applications such as energy storage systems (ESSs), charging stations, and solid-state transformers. However, input power fluctuations, such as those encountered in photovoltaic systems or fuel cells, may reduce the system’s damping and cause oscillations in the converter’s output ...

Transformer Current Ringing in Dual Active Bridge Converters

IEEE Transactions on Industrial Electronics, 2021
In dual active bridge (DAB) converters, there can be transformer current ringing, especially when the transformer turns ratio is high. It is induced by high dv/dt generated by fast switching as well as the low impedance of the magnetic tank at the high-frequency range.
