    Sammanfattning : This paper describes a unique method for the semi-automatic detection of historic charcoal production sites in LiDAR-derived digital elevation models. Intensified iron production in the early 17th century has remarkably influenced ways of how the land in Sweden was managed. LÄS MER

  3. 2. Linear Time Periodic Analysis of Dc-Dc converter

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Nyckelord :HTM; Harmonic Transfer Matrix; HTF; Harmonic Transfer Function; LTP; Linear Time Periodic Systems; PWM; Dc-Dc converter; Pulse Width Modulator; subharmonics; chaos; subharmonic estimation; Technology and Engineering;

    Sammanfattning : Aim of this thesis is to analyze Dc-Dc converters by using the techniques of Linear Periodic Time varying (LTP) systems to estimate the amount of subharmonics injected in the load. Dc-Dc converters are used to transform a Dc input to a Dc output of different voltage. In this thesis we study in particular the so called "switch mode" converters. LÄS MER
