  2. 1. Novel Processing and Electrical Characterization of Nanowires

    Author : Kristian Storm; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Gate; Capacitance; Hall effect; InP; InAs; Characterization; Nanowires; Processing; LED; Transistor; Fysicumarkivet A:2013:Storm;

    Abstract : This thesis investigates novel electrical nanowire characterization tools and devices. Conventional characterization methods, long available to bulk semiconductor samples, have been adapted and transferred to the nanowire geometry. READ MORE

  4. 2. High Voltage DC-biased Oil Type Medium Frequency Transformer; A Green Solution for Series DC Wind Park Concept

    Author : Mohammad Kharezy; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High voltage DC; Offshore wind farm; Dual active bridge; Medium-frequency power transformer; Leakage inductance; Insulation design; HVDC; High power isolated DC DC converter; Parasitic capacitance;

    Abstract : The electric energy generated by remote offshore wind parks is transported to the consumers using high voltage submarine cables. On the generation site, such transmissions are realized today by collecting the energy produced by several wind turbines in a bulky and expensive transformer placed on a dedicated platform.

  5. 3. Voltage Transients in the Field Winding of Salient Pole Wound Synchronous Machines : Implications from fast switching power electronics

    Author : Roberto Felicetti; Urban Lundin; Jon Kjellin; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; apparent resistance; cable modeling; current control; transmission line model; eddy currents; field winding; frequency analysis response; Fourier Transform; impedance mismatch; main inductance; overvoltage; parasitic capacitance; partial discharge; quality factor; ringing; slew rate; stray inductance; voltage gradient; winding resonance frequency;

    Abstract : Wound Field Synchronous Generators provide more than 95% of the electricity need worldwide. Their primacy in electricity production is due to ease of voltage regulation, performed by simply adjusting the direct current intensity in their rotor winding. READ MORE

  6. 4. Automotive Electromagnetic Compatibility - Prediction and Analysis of Parasitic Components in Conductor Layouts

    Author : Sabine Alexandersson; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parasitic components; Electromagnetic Compatibility; Crosstalk; Electromagnetic simulations;

    Abstract : The electronics in the automotive industry is facing a new era where safety critical functions are electrified, as for example drive-by-wire technology. At the same time as the number of electrical loads in the vehicles is increasing, the time to market is decreasing. READ MORE

  7. 5. Modelling and Characterisation of Terahertz Planar Schottky Diodes

    Author : Aik-Yean Tang; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis deals with the modelling and characterisation of THz planar Schottky diodes, focusing on analyses of geometry-dependent electrical parasitics and the thermal management of the diode chip. Moving towards higher operating frequencies, the diode performance degrades due to high frequency losses, parasitic couplings and self-heating effects. READ MORE
