Color neutral nanocomposite nickel-tantalum oxide for electrochromic windows

Andreas Schueler, Josef Andreas Schuler, Olivia Valérie Charlotte Bouvard

Electrochromic windows can darken on demand to limit the solar gains entering a building to reduce the risk of overheating, while preserving the view towards the exterior. Yet, the switching speed and contrast as well as the durability of commercial produc ...

Enabling exact delay synthesis

Giovanni De Micheli, Pierre-Emmanuel Julien Marc Gaillardon, Mathias Soeken, Luca Gaetano Amarù

Given (i) a Boolean function, (ii) a set of arrival times at the inputs, and (iii) a gate library with associated delay values, the exact delay synthesis problem asks for a circuit implementation which minimizes the arrival time at the output(s). The exact ...

Novel Insight into the Output Current Ripple for Multilevel and Multiphase Converter Topologies

Drazen Dujic, Alexandre François Christe

When it comes to the computation / estimation of the switching losses in a multilevel converter, it is crucial to know the instantaneous value of the output current. If the average output current value is used instead, there is a non negligible error when ...
