  1. 21. Enhanced dielectric AC breakdown strength of polyethylene using voltage stabilizing additives

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Klas Esbo; [2016]
    Keywords : cross-linked polyethylene; LDPE; low density polyethylene; polyethylene; voltage stabilizing additives; fast avalanche breakdown; dielectrical breakdown strength; High voltage cable; HVAC; XLPE; Weibull distribution; AC breakdown; materials chemistry; materialkemi; Technology and Engineering; Chemistry;

    Abstract : There is currently a need to increase the voltage level in high voltage transmission and distribution systems in order to transmit power in a more efficient way. However, the insulation of the conductor in high voltage alternating current (HVAC) cables needs to be improved in order to withstand these high voltages. READ MORE

  3. 22. An Economical & Technical Study of the Participation of a Virtual Power Plant on the Swiss Balancing Market : WRITTEN IN COLLABORATION WITH SWISSELECTRICITY

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Romain Bourdette; [2016]
    Keywords : Ancillary services; Virtual Power Plant; Industrial Energy Resources; Standby generators; Secondary and Tertiary control;

    Abstract : The current shift towards renewable energy resources creates volatility in the electricity production that must be compensated by nevi sources of balancing energy. To ensure a normal operation of the power system, the transmission system operators procure power reserves able to provide regulation energy through market processes. READ MORE

  4. 23. Electric field distribution of sphere-plane gaps : A SIMULATION APPROACH

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Michail Michelarakis; [2016]
    Keywords : sphere-plane electrode configuration; electric field; electrostatics; gap distance; breakdown voltage; Finite Element Method FEM ; high voltage testing; sfär-platta elektrodkonfiguration; elektriskt fält; elektrostatik; gapavstånd; genombrottsspänning; Finite Element Method FEM ; högspänningsprovning;

    Abstract : The continuous increase of the voltage levels in power transmission systems has lead to the occurrence of higher switching transients during their operation. The design of equipment and grid components able to sustain such a stressful operation, requires an intensive study of the electric field stress generated by these transients, and their distribution to the vicinity of each configuration.

  5. 24. Vertical heterostructure III-V nanowire MOSFETs

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Adam Jönsson; [2016]
    Keywords : MOSFET; transistor; heterostructure; III-V; RF; semiconductor; silicon; fabrication; electronics; Technology and Engineering;

    Abstract : If cars had developed as fast as processors they would go at 470,000 mph, get 100,000 miles to the gallon, and cost 3 cents" claims Paul Ottelini, Intel CEO 2005-2013. This serves as a reminder of how fast the field of nanoelectronics is developing due to constant demand for faster and more energy efficient integrated circuits. READ MORE

  6. 25. Leakage current and breakdown of HfO2/InGaAs MOS capacitors

    University essay from Lunds universitet/Fysiska institutionen

    Author : Edvin Winqvist; [2015]
    Keywords : breakdown; leakage; ingaas; hfo2; Physics and Astronomy;

    Abstract : With the constant downscaling of transistors, silicon as a production material is falling out of favour because of increasing power consumption when the size of devices becomes smaller. Compound materials from group III-V in the table of elements are promising candidates to replace silicon. READ MORE
