1. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. READ MORE

2. Investigation of switching power losses of SiC MOSFET : used in a DC/DC Buck converter
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : All DC/DC converter products include power electronic circuits for power conversion.It is important to find an efficient way for power conversion to reduce power losses and reduce the need for cooling and achieve environmentally friendly solutions.The use of semiconductor switches of wide band gap type is a solution to the problem.

3. Temperature Dependent Electrical Characterisation of Vertical InAs-InGaAs Nanowire MOSFETs
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : This thesis presents the temperature dependence of InGaAs Nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs) grown at two different temperatures. The two different growths represent one sample having nanowires which have a mixed crystal structure (showing stacking faults) and one sample with nanowires of pure crystal structure (without stacking faults).

4. Evaluation of DC Fault Current in Grid Connected Converters in HVDC Stations
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : The main circuit equipment in an HVDC station must be rated for continuous operation as well as for stresses during ground faults and other short circuits. The component impedances are thus selected for proper operation during both continuous operation and short circuit events. READ MORE

5. Design 50MW large scale PV power plant considering Bangladeshi climate
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : Conventional electricity production is undergoing a major transition, and renewable energy projects are playing an important part in this shift. An opportunity exists to use the naturally high solar radiation resource to meet the high electricity demand. READ MORE
