21. Main Circuits, Submodules, and Auxiliary Power Concepts for Converters in HVDC Grids
Abstract : In order to enable the massive introduction of renewable energies the need for high-voltage direct current (HVDC) grids is anticipated. Large, globally interconnected HVDC networks will likely be the most cost-efficient means to balance electricity demand and available generation. READ MORE

22. Modeling and Implementation of Current-Steering Digital-to-Analog Converters
Abstract : Data converters, i.e., analog-to-digital converters (ADCs) and digital-to-analog converters (DACs), are interface circuits between the analog and digital domains. They are used in, e. READ MORE

24. EMI from Switched Converters – Simulation Methods and Reduction Techniques
Abstract : In this thesis, the conducted EMI from switched power converters has been analyzed using various existing models, own-derived models as well as measurements. The ingoing passive components in a switching converter have been modeled with respect to their high frequency behavior and the static and dynamic behavior of the active semiconductors has been analyzed.

25. Modeling Analog to Digital Converters at Radio Frequency
Abstract : Det här arbetet handlar om att ta fram beteendemodeller av analog till digital omvandlare avsedda för tillämpningar i radiofrekvensområdet. Det gäller tillämpningar inom telekommunikation men även in test- och mätinstrument där omvandlingen från analoga till digitala signaler ofta är en prestandamässig flaskhals. READ MORE
