3. 2. Magnetic field separation for current prediction in three-phase systems : Regression-based current prediction

   Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

   Författare :Sara Lenman; Sofia Blaad; [2023]
   Nyckelord :Alternating Current; Crosstalk Separation; Magnetic field sensors; Regression; Sensor technology; Three-phase system;

   Sammanfattning : Current controls the motion of a manipulator. The manipulators at ABB are powered by a three-phase alternating current system where shunt resistors are utilised to measure the current to the motors. Magnetic field sensors are instead investigated to eliminate issues with power losses, the number of components and the cost of the shunt resistors. LÄS MER

4. 3. Adversarial Machine (Deep) Learning-basedRobustification in 5G Networks

   Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

7. 5. A Novel Two-Level Inverter Design for Efficient Energy Conversion in a Maglev Train Rail

   Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

   Författare :Oskar Zetterström; Stefan West Westholm; [2023]
   Nyckelord :IGBT; Inverter; Gate-driver; Prototype; Pulse width modulation; Sine wave; Maglev train; IGBT; Växelriktare; Grinddrivenhet; Prototyp; Pulsbreddsmodulering; Sinusvåg; Maglevtåg;

   Sammanfattning : This report covers the construction of a prototype inverter system designed to power the rail of a maglev train, from component selection through simulations and power demands to mounting and wiring the components into a cabinet. The inverter is made with insulated gate bipolar transistors controlled with pulse-width modulated signals provided by a custom microcontroller. LÄS MER
