Reconfigurable dual active bridge converter for aircraft applications

2012 Electrical Systems for Aircraft, Railway and Ship Propulsion, 2012
The increase of electrical energy consumption in modern aircrafts stimulates manufactures to install a 540V DC bus in future aircrafts, together with the existing 270V and 28V DC buses. Energy transferred between the high voltage DC bus (HVDC, 270V) and the low voltage DC bus (LVDC, 28V) is made by bidirectional isolated DC-DC converters.

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.
