1. 1. Pulse-width voltage modulation in the Python-based open-source simulator Motulator : A Realization of SVPWM, Harmonic analyzer and Over-modulation on Two and Three-level Inverters, and a Solution for Unbalanced Neutral Point Voltage on Three-level Inverters

   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

5. 4. Stock market analysis with a Markovian approach: Properties and prediction of OMXS30

   University essay from KTH/Matematisk statistik

   Author : Max Aronsson; Anna Folkesson; [2023]
   Keywords : Markov chain; OMXS30; Markov chain properties; voting ensemble model; markovkedja; OMXS30; egenskaper hos markovkedjor; ensemble-modell;

   Abstract : This paper investigates how Markov chain modelling can be applied to the Swedish stock index OMXS30. The investigation is two-fold. Firstly, a Markov chain is based on index data from recent years, where properties such as transition matrix, stationary distribution and hitting time are studied. READ MORE

6. 5. Does an increase in household debt lead to an increase in inflation? : An empirical study examining the relationship between household debt and inflation

   University essay from Umeå universitet/Nationalekonomi

   Author : Patrik Jonsson; [2023]
   Keywords : ;

   Abstract : Since the 2000s, there has been an upward trend in household debt on a global scale. This paper aims to investigate if the rise in household debt leads to increased inflation via debt-driven consumption. This is to contribute to the lacking research field and gain new perspectives on macroeconomic implications of excessive household debt. READ MORE
