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-

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.
