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.

Nonlinear Implementable Control of a Dual Active Bridge Series Resonant Converter [PDF]

IEEE Transactions on Industrial Electronics, 2022
This paper presents a novel control strategy for a Dual Active Bridge Series Resonant Converter (DAB-SRC). The strategy seeks to ensure the stability of the converter over its entire dynamic range while enhances the transient response. Both properties allow the use of the converter in new applications where fast dynamics are required, surpassing the ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
