Power Quality Optimization in Dual Active Bridge Converters

open access: yesIEEE 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 ...

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

open access: yesFEBS 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
