1. High Efficiency Inductive Power Transfer Systems for Vehicle Charging
Sammanfattning : Awareness of climate change due to greenhouse gas emissions and air pollution has led to a transition from internal combustion engine vehicles to electric vehicles. Wireless charging by inductive power transfer is a promising solution for charging electric vehicles. LÄS MER
2. Evaluation of different topologies for high-power dc-dc converters
Sammanfattning : .... LÄS MER
3. Efficient Simulation Methods of Large Power Systems with High Penetration of Renewable Energy Resources : Theory and Applications
Sammanfattning : Electrical energy is one of the most common forms of energy these days. Consequently, electric power system is an indispensable part of any society. LÄS MER
4. Modeling, Control and Protection of Low-Voltage DC Microgrids
Sammanfattning : Current trends in electric power consumption indicate an increasing use of dc in end-user equipment, such as computers and other electronic appliances used in households and offices. With a dc power system, ac/dc conversion within these loads can be avoided, and losses reduced. LÄS MER
5. High-Efficiency SiC Power Conversion : Base Drivers for Bipolar Junction Transistors and Performance Impacts on Series-Resonant Converters
Sammanfattning : This thesis aims to bring an understanding to the silicon carbide (SiC) bipolar junction transistor (BJT). SiC power devices are superior to the silicon IGBT in several ways. They are for instance, able to operate with higher efficiency, at higher frequencies, and at higher junction temperatures. LÄS MER
