  1. 21. Active rectification and control of magnetization currents in synchronous generators with rotating exciters : Implementation of the SVPWM algorithm using MOSFET technology

    University essay from Uppsala universitet/Elektricitetslära

    Author : Tomas Johansson; [2015]
    Keywords : rectification; SVPWM; space vector pulse width modulation; current control; active rectification; three phase;

    Abstract : This thesis aims to design and build a power electronics system for the rectification and control of magnetization currents in synchronous generators with rotating exciters.The rotating exciter provides three-phase AC while the generator rotor needs DC with a high degree of control.

  3. 22. PFC-design for frequency converter

    University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska högskolan

    Author : David Kantzon; [2015]
    Keywords : ;

    Abstract : This thesis deals with power factor correction for three-phase systems. A boost-buck topology was described, modeled and then simulated in MATLAB/Simulink. The simulation results show that the system provides a power factor over 99% over the tested power output range. READ MORE

  5. 24. Signal Processing of DC/DC converter inductor current measurement

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Yinjia Li; Zakir Hussain Ranizai; [2013]
    Keywords : Signal processing; Buck converter; filter design; slope; average value; DC DC converter;

    Abstract : This thesis is one part of ongoing research project of Ericsson AB together with Blekinge institute of technology on the aspect of Ericsson Power modules. The aim of this project is to apply signal processing method on the measured current signal of inductor component of Ericsson BMR 450 Buck converter by using software Matlab, the method should be able to remove the noisy part which exists on the measured signal, so the signal can be undulated within normal range.
