  1. 1. Gate driver solutions for high power density SMPS using Silicon Carbide MOSFETs

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Farhan Akram; [2021]
    Keywords : SiC MOSFETs; Gate drivers; DC-DC converter; High power and efficiency power supplies;

    Abstract : Discrete silicon carbide (SiC) power devices have unique characteristics that outpace those of silicon (Si) counterparts. The improved physical features have provided better faster switching, greater current densities, lower on-resistance, and temperature performances. READ MORE

  3. 2. Optimizing a servo drive using Field Oriented Control

    University essay from Uppsala universitet/Solcellsteknik

    Author : Lukas Land; [2021]
    Keywords : antenna; servo; foc; pmsm; vector engine; field oriented control; electrical motor; servo; fältorienterad kontroll; elmotor;

    Abstract : An optimization of a servo system for a satellite antenna system wasperformed. A brushless DC motor with an angle encoder was used, whoseangular velocity had to be controlled with great precision. Specializedhardware was used to implement field oriented control to directlycontrol the torque and magnetic flux of the motor. READ MORE

    University essay from Högskolan i Halmstad/Akademin för hälsa och välfärd; Högskolan i Halmstad/Akademin för hälsa och välfärd

    Author : Malin Svennerlind; Sewit Hagos; [2021]
    Keywords : allsvenskan; coping strategies; Covid-19; division 1; dual career in sport and studies; football; motivation; superettan; stressors; allsvenskan; Covid-19; division 1; dubbla karriärer i sport och studier; fotboll; motivation; stresshantering; stressorer; superettan;

    Abstract : Dual career (DC) means that an athlete combines sport and study/work. A balanced DC strongly depends on an athlete's ability to cope with stressors and is of paramount importance to succeed with both studies and sport (Stambulova et al., 2015; Wylleman & Reints, 2010). READ MORE

  6. 5. WIDE RANGE BI-DIRECTIONAL DC-DC CONVERTER

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Ali Rezaee; [2021]
    Keywords : Keywords: Bidirectional Converter; Phase Shifted Full Bridge; Soft Switching; Wide Input–WideOutput;

    Abstract : Bi-directional DC-DC converters are used for applications that require a flow of energy in two directions, while a wide range converter offer efficient operation over a wide range of input and output voltages. However, an efficient technology that is both bi-directional and Wide Input Wide Output (WIWO), currently, does not currently exist. READ MORE
