Nanomechanical systems developed at TU Wien have now reached a level of precision and miniaturization that will allow them to ...

Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

Abstract: In switching converters, capacitor current is a critical feedback parameter due to its ability to rapidly reflect dynamic load variations, making it widely applicable in various control ...

Abstract: High-power flexible dc links employ modular multilevel converters (MMC) for compact active power redirection in medium and high voltage grids. During contingencies, such converters may need ...
