    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermoelectricity; Power converter; Silicon Carbide; MOSFET; Power management; Thermoelectric generator; Renewable energy; Vehicle; Power electronic; Waste heat; Ultra-low inductance; Power module; Termoelektrisk energiomvandling; Kiselkarbid MOSFET; Effektomvandlare; Förnybar energikälla; Effektelektronik; Spillvärme; Effektmodul; Låg induktiv module; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Energy consumption in the world has increased continuously due to a growing population and increased energy consumption per capita. Moreover, the largest part of consumed energy still comes from fossil sources which in 2016 was more than 130 PWh. READ MORE

  4. 2. Control Strategy for Energy Efficient Fluid Power Actuators : Utilizing Individual Metering

    Author : Björn Eriksson; Jan-Olov Palmberg; Jonas Larsson; Jochen Pohl; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid power; mode switch; energy efficient; independent metering; split spool; poppet; Fluid mechanics; Strömningsmekanik;

    Abstract : This thesis presents a solution enabling lower losses in hydraulic actuator systems. A mobile fluid power system often contains several different actuators supplied with a single load sensing pump. One of the main advantages is the need of only one system pump. This makes the fluid power system compact and cost-effective. READ MORE

  5. 3. High power bipolar junction transistors in silicon carbide

    Author : Hyung-Seok Lee; Carl-Mikael Zetterling; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon Carbide SiC ; power device; biplar junction transistor; TiW; ohmic contact; current gain; Electronics; Elektronik;

    Abstract : As a power device material, SiC has gained remarkable attention to its high thermal conductivity and high breakdown electric field. SiC bipolar junction transistors (BJTs) are interesting for applications as power switch for 600 V-1200 V applications. READ MORE

  6. 4. Reliability in performance-based regulation

    Author : Torbjörn Solver; Lennart Söder; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Performance-Based Regulation; Distribution System; Power System Reliability; Monte Carlo Simulations; Quality of Supply; Electric power engineering; Elkraftteknik;

    Abstract : In reregulated and restructured electricity markets the production and retail of electricity is conducted on competitive markets, the transmission and distribution on the other hand can be considered as natural monopolies. The financial regulation of Distribution System Operators (DSOs) has in many countries, partly as a consequence of the restructuring in ownership, gone through a major switch in regulatory policy.
