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.

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 ...
