1. 1. Designing a Low Power Regulator for Smart Dust

   Master-uppsats, Linköpings universitet/Elektroniksystem

   Författare :Mohamed Lababidi; [2013]
   Nyckelord :communication; electronics; smartdust; regulator; low power; 65-nm;

   Sammanfattning : The revolutionary progress that happened recently in the micro-electro mechanicalsystems (MEMS) field and the complementary metal-oxide-semiconductor(CMOS) integrated circuits has made it possible to produce low-cost, low-powerand small size processing circuits. Utilizing wireless communication theory allowsthose circuits to send their data over a network. LÄS MER

3. 2. Identification of process induced defects affecting the performance of nanowire based solar cells by spatially resolved photocurrent measurements

   Master-uppsats, Lunds universitet/Fasta tillståndets fysik

   Författare :Calvin Kan; [2013]
   Nyckelord :solar cells; Nanowires; nanotechnology; sustainable development; photocurrent measurements; energy; Technology and Engineering;

   Sammanfattning : Solar power clearly has one of the greatest potential among renewable energy but a big setback is that it is still relatively expensive. Engineering of materials on a nanoscale, e.g. LÄS MER

4. 3. IGCT Transient Analysis and Clamp Circuit Design for VSC valves

   Uppsats för yrkesexamina på avancerad nivå, KTH/Elektrisk energiomvandling

   Författare :Sanchit Singh; [2012]
   Nyckelord :;

   Sammanfattning : In today’s high power VSCs (Voltage Source Converters), IGBTs (Insulated Gate Bipolar Transistors) are the dominant semiconductors. These converters are in general modular multilevel based and contain several building blocks that are series connected. Each of these building blocks in turn consist of several series connected IGBT valves. LÄS MER

5. 4. Power Loss Modeling of Isolated AC/DC Converter

   Master-uppsats, KTH/Elektrisk energiomvandling

   Författare :Naveed Ahmad Khan; [2012]
   Nyckelord :;

   Sammanfattning : Several research activities at KTH are carried out related to Isolated AC/DC converters in order to improve the design and efficiency. Concerning the improvement in the mentioned constraints, losses of the elements in the prototype converter are modeled in this thesis work. LÄS MER

7. 5. Simulation of Avalanche breakthroughin Si and SiC

   Kandidat-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Författare :Alex Ellgren; [2012]
   Nyckelord :;

   Sammanfattning : This paper describes a Monte Carlo simulation of avalanche breakthrough in Si and SiC, which is intended as a teaching aid in introductory courses on semiconductor devices. The model used approximates the charge carriers as hard balls bouncing o each other and transferring kinetic energy between themselves, with ionizations being recorded when EKin > Eg. LÄS MER
