AC-DC DAB Converter with Power Factor Correction

Energies, 2022
AC-DC conversion is required in many applications, and in some of them isolation is strictly required, certainly while maintaining characteristics such as a high power factor and low input current THD. In this paper, an AC-DC converter, comprising a full-bridge diode rectifier and a dual-active-bridge (DAB) converter, is utilized to fulfill these ...

Peak Current Control and Feed-Forward Compensation for the DAB Converter

2019 IEEE International Conference on Industrial Technology (ICIT), 2019
This paper presents a double band peak current control for the DAB converter that permits to avoid the risk of transformer saturation. Additionally, feed-forward compensation is employed to achieve a fast transient response under load variations. The proposal is described, analyzed, and numerically simulated.

Efficiency optimisation of ZVS isolated bidirectional DAB converters [PDF]

IET Power Electronics, 2018
This study presents a control method for isolated bidirectional dual‐active‐bridge converters to optimise the efficiency by achieving the zero‐voltage switching (ZVS) in high‐voltage applications, which the switching losses are the major issues. At light‐load condition, the duty control algorithm is proposed to achieve the ZVS for all switches while ...
