  1. 1. Off-State Stress Effects in AlGaN/GaN HEMTs : Investigation of high-voltage off-state stress impact on performance of and its retention in hybrid-drain ohmic gate AlGaN/GaN HEMTs

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ivan Krsic; [2023]
    Keywords : HEMT; GaN; off-state stress; memory effects; drain leakage current; dynamic RDSon; threshold voltage instabilities; charge redistribution; HEMT; GaN; stress i avslaget tillstånd; minneseffekter; läckströmmen; dynamisk RDSon; instabiliteten hos styrets tröskelspänning; omfördelningen av laddningar;

    Abstract : High electron mobility transistors (HEMTs) realized using AlxGa1-xN/GaN are relatively new technology which is prominent for high-speed and high-power applications. Some of the main problems with this technology were identified as dynamic RDSon, current collapse and threshold voltage instabilities due to the off-state stress. READ MORE

  3. 2. Virtual power lines in the future Swedish power system

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Simon Hessman; Frida Lundberg; [2023]
    Keywords : VPL Virtual Power Line Nordic44 Nordic46 BESS Energy Storage; Technology and Engineering;

    Abstract : The transition towards renewable energy and electrification is expected to accelerate in the coming decades. This change is being studied by several actors, in Sweden most notably by Svenska kraft- nät, the Swedish TSO. READ MORE

  4. 3. Velocity Control of a Mobile Charger in a Wireless Rechargeable Sensor Network

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Emilia Haltorp; [2023]
    Keywords : Wireless Sensor Networks; Mobile Charger; Wireless Energy Transfer; Traveling Salesman Problem; Trådlösa Sensornätverk; Mobil laddare; Trådlös strömöverföring; Handelsresandeprobleme;

    Abstract : Wireless sensor networks (WSN) are one of the most rapidly evolving technical areas right now. They can be used in a lot of different applications, environmental monitoring and health applications being two examples. The sensors can be placed in hazardous and remote environments since there is no need for cabling or manual maintenance. READ MORE

  5. 4. Model-Observation Comparisons of O+ Concentrations in the Martian Ionosphere

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Chinmaya Nagar; [2023]
    Keywords : MAVEN; NGIMS; Martian; Ionosphere; Fehsenfeld; Tenewitz;

    Abstract : A few years ago, the charge-transfer reaction CO2+  +  O ⟶ O+ + CO2 was investigated experimentally for the first time since the study by Fehsenfeld et al., (1970). This new investigation was conducted by Tenewitz et al., (2018). READ MORE

  6. 5. Ion and ENA precipitation onto the upper atmosphere of Venus : Estimate of precipitation maps using data from a hybrid model

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Lorenzo Obersnel; [2023]
    Keywords : Eneregetic Neutral Atoms; Venus; Ion precipitation; ENA precipitation; Atomi Neutri Energetici; Venere; precipitazione di ioni; precipitazione di atomi neutri; Energisk Neutral Atom; Venus; Utfällningen joner; Utfällningen Energisk Neutral Atom;

    Abstract : Venus does not have a strong intrinsic magnetic field as the Earth, and its magnetosphere is induced by the interaction of the solar wind with the ionosphere. The near-Venus space environment is characterized by the presence of a bow shock and of an induced magnetic boundary linked to the interplanetary magnetic field orientation. READ MORE
