Reconfigurable dual active bridge converter for aircraft applications

open access: yes2012 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.
