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

    Author : Jiale Deng; [2023]
    Keywords : Three-level inverters; over-modulation techniques; space vector modulation; neutral-point voltage balancing; non-uniform Fourier transform; Trenivåväxelriktare; övermodulation; spacevektormodulering; balansering av nollpunktsspänning; olikformig Fouriertransform;

    Abstract : Controlling the dynamic outputs of electrical machines has always been an essential topic in aerospace, automotive and other industries. Electrical machine control consists of several components, each of which can be controlled in various ways. Whereas the dynamic responses are mostly simulated using MATLAB/SIMULINK, Prof. READ MORE

    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

  4. 3. Evaluation of white-light generation as possible seed for a mid-infrared optical parametric chirped pulse amplifier

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

    Author : Chuang Lu; [2017]
    Keywords : nonlinear linear optics; ultrafast optics; Mid-infrared generation; near-infrared; Optical parametric amplification; Optical Parametric Chirped-pulse Amplification; supercontinuum generation; white-light generation; laser induced filamentation; Dispersion-scan; nonlinear propagation; Physics and Astronomy;

    Abstract : White-light spectra of different crystals, based on 1030-nm intense pump pulses have been investigated in order to derive a near-infrared seed for mid-infrared generation. Among ten crystals, YAG (yttrium aluminium garnet), KGW (potassium gadolinium tungstate) and YVO4 (yttrium orthovanadate) exhibit the most suitable properties for supercontinuum generation with high efficiency for spectral broadening as well as high tolerance to optical damage.

  5. 4. Modelling of Damaged Material and Experimental Pulse Propagation through a Nonlinear Layer

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Mattias Johansson; Jimmy Carlsson; Jonas Olofsson; [2002]
    Keywords : Acoustic response; mesoscopic modelling; pulse propagation; local interaction simulation; dynamic pulse modulation.;

    Abstract : In order to understand and develop the knowledge about nonlinear behaviour of materials one need to combine some physical procedures, like theoretical modelling, simulations and experimental verification to get a better understanding of the materials. This Thesis work consists of two separate parts. READ MORE
