Abstract [en]

The thesis is to develop Signal Processing methods which increase the performance, functionality and reliability of dc-dc converters which is part of an ongoing project of Ericsson together with Blekinge Institute of Technology. The aim of this project is to model the buck converter system of Ericson’s BMR450 using MATLAB Simulink and develop methods to identify the capacitive load. Our first approach is to derive the equation which gives relation of capacitive load with output voltage in time domain analysis. Our second method deals with resonant point of frequency response of buck converter using Linearization method. Our final method deals in frequency domain analysis using FFT. For different values, we calculated the capacitive load values using proposed methods and compared them to the original values to observe the percentage of errors.
