  1. 1. Commissioning and Testing of a Novel Buck-Boost Phase-Modular Three-Phase AC/DC Converter with Low Component Number

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

    Author : Saransh Chhawchharia; [2022]
    Keywords : ;

    Abstract : In this thesis, a 1kW hardware prototype of a three-phase inverting buck-boost converter, termed as 6 Switch Buck-Boost Y-Inverter (6YI) is commissioned and tested. The 6YI is designed to be used as a motor drive for renewable energy applications such as fuel cell, solar etc powered motor drives with wide input voltage capability. READ MORE

  3. 2. Visualization of digital modulation techniques

    University essay from Malmö universitet/Institutionen för datavetenskap och medieteknik (DVMT)

    Author : Mustafa Can Tas; Fatima AlKurdi; [2021]
    Keywords : ;

    Abstract : Digital communication has gone through much development in the past decade. The literature in this field has developed and improved as well, but the educational materials still lack illustrative descriptions. READ MORE

  4. 3. Current Control and Modelling of an Inspiration Valve

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

    Author : Astrid Lindstedt; [2021]
    Keywords : Current Servo; Cascade Control; Solenoid Model; Ventilator; Strömregulator; Kaskadreglering; Solenoid modell; Respirator;

    Abstract : An analog current servo of an intensive care ventilator is being developed at Getinge in Stockholm. The current servo is used to control the output gas flow of an inspiration valve to a patient’s lungs. The ventilator’s control system is in a cascade design of two closed-loops, of which the current servo is the controller for the inner loop. READ MORE

  5. 4. Efficient Transmission over Unknown Channels

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

    Author : Ranjitha Gubbi Suresh; [2020]
    Keywords : Multi-Layer Transmission; RBIR; HARQ; mixing layers; successive demodulation; Wi-Fi; Technology and Engineering;

    Abstract : In recent years, digital transmission techniques have been continuously evolving by employing increasingly more advanced Modulation and Coding Scheme (MCS). However, when the wireless channel is varying rapidly, it is hard or even impossible for the transmitter to select the proper MCS. READ MORE

  6. 5. Optical FRAME: Investigating the effects of filtering the optical Fourier domain to be used as a new approach for FRAME

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

    Author : Sam Taylor; [2020]
    Keywords : Fourier Optics FRAME Ultra-fast imaging; Physics and Astronomy;

    Abstract : Many important scientific phenomena require ultra-fast imaging to understand and investigate the characteristics of the event. Current methods of ultra-fast imaging that can obtain femtosecond time resolution rely on repeatable events or limiting the techniques versatility by completely remove the use of a dimension e.g. colour.
