1. 1. Efficiency Comparison between a Two-level and an NPC Inverter for Automotive Application

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

   Author : Simon Schneider; [2022]
   Keywords : NPC; 800 V; Efficiency; Automotive; Comparison; SiC; NPC; 800 V; Effektivitet; Bil; Jämförelse; SiC;

   Abstract : De flesta nuvarande elfordon drivs med en systemspänning på 400V. En ökning av denna spänning skulle dock bland annat kunna möjliggöra en kortare laddningstid för fordonets batteri. Den högre systemspänningen medför ett antal utmaningar, varav en är att öka spänningsblockeringsförmågan hos spänningsomvandlarens transistorer. READ MORE

   Keywords : Interior permanent magnet synchronous motor; Continuous control set-Model predictive control; Linear quadratic regulator; Quadratic programming; Interior permanent magnet synchronous motor; Continuous control set-Model predictive control; Linear quadratic regulator; Quadratic programming;

   Abstract : The thesis provides design methods for developing Continuous Control SetModel Predictive Control and Linear Quadratic Regulator for Interior mounted Permanent Magnet Synchronous Motor drive. The software for these controllers are implemented in the prototype motor at China Euro Vehicle Technology (CEVT) to estimate the computation time. READ MORE

4. 3. Efficiency Comparison between Two-Level and T-Type Inverter for 800 V Automotive Application

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

   Author : Rishabh Jain; [2022]
   Keywords : Electric Vehicles; Efficiency Comparison; Loss Calculation; SiC MOSFET; T-Type Inverter; Three-level Inverter; Two-level Inverter; Inverter i två nivåer; inverter av T-typ; inverter i tre nivåer; SiC MOSFET; förlustberäkning; verkningsgradsjämförelse; elfordon;

   Abstract : The falling cost of batteries, along with an increasing need to cut emissions, has spurred significant interest in the electrification of vehicles. In addition, as semiconductor devices have evolved, the research for electric vehicles with higher battery voltage has increased. READ MORE

5. 4. Implementation of Nodes in HVDC Grids

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

   Author : Johanna Olsson; [2020]
   Keywords : HVDC transmission; inverter; pulse width mod-ulation inverters; pulse width modulation; power quality; har-monics; bipolar switching; unipolar switching; total harmonicdistortion;

   Abstract : This project is made for a deeper understanding ofhow frequency and amplitude of the waves that create the controlwave in a Pulse Width Modulated 2-level inverter affect the powerquality and power losses. The results were that a high frequencyreduces the Total Harmonic Distortion but increases the powerloss. READ MORE
