2. 1. Towards Low-Voltage, High-Current : A pioneering drive concept for battery electric vehicles

   Author : Stefan Haller; Kent Bertilsson; Bengt Oelmann; Peng Cheng; Dieter Gerling; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low voltage; high current; EV; BEV; electrical machine; power electronics; MOSFET;

   Abstract : The first electric low-voltage vehicles were constructed in the mid-19th century, but by the early 20th century they were progressively replacedby successors with internal combustion engines. As the consequences ofusing fossil fuels are better understood, our society is now transitioning back. READ MORE

4. 2. Thermoplastic Insulation for High Voltage Cables

   Author : Yingwei Ouyang; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyethylene; insulation; polypropylene; blends; thermoplastic; high voltage; polymer;

   Abstract : High voltage direct current (HVDC) cables that seamlessly integrate renewables have an important contribution to the modern world’s efforts towards a more sustainable future. Extruded HVDC cables that efficiently and reliably transport electricity require robust insulation materials with good thermomechanical and dielectric properties. READ MORE

5. 3. Control and Design Aspects of Components and Systems in High-Voltage Converters for Industrial Applications

   Author : Per Ranstad; Hans-Peter Nee; Alfred Rufer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-voltage converter; resonant converter; high-voltage transformer; transformer parasitics; IGBT; soft-switching; control; Electric power engineering; Elkraftteknik;

   Abstract : High-frequency dc-dc converters are widely used in power electronic applications, both in consumer products and industrial products. By operating the converter at higher frequencies both a smaller size and better control characteristics can be obtained. READ MORE

6. 4. Computational framework for studying charge transport in high-voltage gas-insulated systems

   Author : Shailendra Singh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drift diffusion equation; gaseous dielectrics; high voltage; gas discharge; low temperature plasma; streamer propagation;

   Abstract : Increasing demands in electric energy stimulates a shift in functional requirements to power distribution networks and pushes equipment manufacturers to develop highly optimized products where high rated parameters (e.g., energy, voltages) are combined with reduced geometrical dimensions of components.
