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.

Stability analysis of digitally controlled dual active bridge converters
Journal of Modern Power Systems and Clean Energy, 2017 The dual active bridge (DAB) converters are widely used in the energy storage equipment and the distributed power systems. However, the existence of switching nonlinearity and control delay can cause serious stability problem to the DAB converters. Thus,
