11. Gate driver solutions for high power density SMPS using Silicon Carbide MOSFETs
Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktionSammanfattning : Discrete silicon carbide (SiC) power devices have unique characteristics that outpace those of silicon (Si) counterparts. The improved physical features have provided better faster switching, greater current densities, lower on-resistance, and temperature performances. LÄS MER
12. Model verification and common mode current analysis of grid connected three phase two level converters
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automationSammanfattning : In this Master’s thesis an in-depth model of a shunt active filter for high frequency analysis is constructed. The purpose is to enable analysis of higher frequency behavior reaching 1MHz. Using the high frequency model, common mode currents can be simulated. LÄS MER
13. EMC/EMI i solcellssystem : Minimering av elektromagnetiska störningar från solcellsanläggning
Kandidat-uppsats, Karlstads universitetSammanfattning : This report presents a theoretical background to electromagnetic interference from photovoltaic systems that use power optimizers. The purpose is to carry out measurements at an existing facility to analyze and discuss appropriate measures to minimize disturbance levels. LÄS MER
14. Evaluation of Strain and Temperature Measurements with Fiber Bragg Grating for Loss Verification and Heat Transfer of Ball Bearings
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Volvo Cars is in a change of producing only electric and hybrid cars by 2025.Subcomponent testing is a crucial part to ensure the quality of the individual buildingblocks in an electric machine. Any way of making these tests more reliable and less timeconsuming is of great interest at Volvo. LÄS MER
15. Light Rail Camera - an EMC-assessment
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : When installing multiple security cameras the cable management can be a struggle. Historically cameras need one cable for power and one for communication, however, advancements in power over ethernet have reduced the number of cables down to one. LÄS MER
