4. 2. Design of Thermoelectric Generators for Automotive EGR Applications

   Author : Olle Högblom; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contact resistances; Exhaust gas heat recovery; Thermoelectrics; CFD;

   Abstract : Rising energy prices and greater environmental awareness along with stringent emissions legislation in the automotive industry make it possible to introduce techniques in the aftertreatment system that have previously been unprofitable. One such technique, studied in this work, is heat recovery in the exhaust gas recirculation (EGR) cooler using thermoelectric generators (TEG). READ MORE

5. 3. Vertical High-Voltage Transistors on Thick Silicon-on-Insulator

   Author : Ulrich Heinle; Gehan Amaratunga; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; SOI; vertical DMOS; trench isolation; power electronics; integration; on-resistance; capacitive coupling; self-heating; switching; Elektronik; Electronics; Elektronik; Elektronik; Electronics;

   Abstract : More and more electronic products, like battery chargers and power supplies, as well as applications in telecommunications and automotive electronics are based on System-on-Chip solutions, where signal processing and power devices are integrated on the same chip. The integration of different functional units offers many advantages in terms of reliability, reduced power consumption, weight and space reduction, leading to products with better performance at a hopefully lower price.

6. 4. Modelling of High Power SOI Vertical DMOS Transistors and Flip-chip Packages

   Author : Kuntjoro Pinardi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Conductive Adhesive; self-heating; Unclamped Inductive Switching; ACA; vertical DMOS; integration; Flip-chip; UIS; SOI;

   Abstract : Part I: Vertical DMOS Transistors System level integration is a major trend in the electronic industry at the moment. For automotive applications in particular it is desirable to integrate CMOS logic circuits and different types of power devices. READ MORE

7. 5. Internal Tar/CH4 Reforming in Biomass Dual Fluidised Bed Gasifiers towards Fuel Synthesis

   Author : Kristina Göransson; Per Engstrand; Wennan Zhang; Kevin J Whitty; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Allothermal gasification; Bio-automotive fuels; Biomass gasification; Catalytic bed-material; Dual fluidised bed; Ni-catalyst; Syngas cleaning; Tar removal; Tar CH4 reforming;

   Abstract : Production of high-quality syngas from biomass gasification in a dual fluidised bed gasifier (DFBG) has made a significant progress in R&D and Technology demonstration. An S&M scale bio-automotive fuel plant close to the feedstock resources is preferable as biomass feedstock is widely sparse and has relatively low density, low heating value and high moisture content.
