  1. 6. A design of a 100 MS/s, 8-bit Pipelined ADC in CMOS

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

    Author : Shen Zhang; [2021]
    Keywords : Technology and Engineering;

    Abstract : The thesis focuses on designing and simulating an 8-bit high-speed fully differential pipelined Analog to Digital Converter (ADC) in the 65nm Complementary Metal-Oxide-Semiconductor (CMOS) technology by using the software Cadence Virtuoso. The aim is to increase the operation speed of the ADC for communication systems without reducing the performance, in the meantime, the low power consumption and the low complexity should also be required when considering future implementation.

  3. 7. 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

  4. 8. The Effect of Harmonics on the Electrical Grid due to Electric Vehicle Chargers

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Ingemar Solander Araúz; [2020]
    Keywords : Examensarbete Elektroteknik; elnät; övertoner; elbilsladdare; transformator förluster; Bachelor thesis electrical engineering; harmonics; electrical grid; electric car charger; transformer loss;

    Abstract : In this thesis the effect of harmonics on the electrical grid from electric car chargers, specifically the effect on distribution transformers, is analyzed. The study was performed on the electrical grid of two areas provided by the electrical company Dala Energi. READ MORE

  5. 9. Evaluation of the wavefronts and spatial structures of ultrashort pulses passing through a micro-channel plate

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Simon Ek; [2019]
    Keywords : high-order harmonic generation; HHG; micro-channel plate; MCP; attophysics; Physics and Astronomy;

    Abstract : The first aim of this project is to make high-order harmonic (HHG) setups more compact and user-friendly, by including a micro-channel plate (MCP). Simulations of the transmission properties of an MCP has been performed. These simulations displayed introduced structure in the far field, but a very well behaved beam in the near field. READ MORE

  6. 10. Model Predictive Control of Electric Drives -Design, Simulation and Implementation of PMSM Torque Control

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

    Author : Levente Zsolt Pap; [2018]
    Keywords : PMSM; Field Oriented Control; Model Prediction Control; Inverter; Electric Drive; DSP;

    Abstract : The thesis deals with the design of a permanent magnet synchronous machine controller that isimplemented on an embedded platform to replace the off-the-shelf controller currently being used in theelectric race car of the KTH Formula Student team. Software implementation of the control algorithmwas tested in laboratory environment on the hardware prototype of a 2-level three-phase voltage sourceinverter. READ MORE
