  1. 1. Development of new criteria for train detection and evaluation in critical conditions

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Sofiane Kerbal; [2019]
    Nyckelord :railway signaling; train detection; track circuit; shunt; frequency modulation; frequency-shift keying modulation; third-order harmonic; short-time Fourier transform; power spectral density estimation; cross-correlation;

    Sammanfattning : Railway signaling is of paramount importance to ensure traffic management andsafety on the rail network. The main lines are divided into sections called ‘blocks’,which are governed by a fixed signal installation. To prevent trains from colliding,each block allows one train at once. LÄS MER

  2. 2. Low Frequency Simulation of Traction System for EMC Analysis

    Master-uppsats, Linköpings universitet/ReglerteknikLinköpings universitet/Tekniska högskolan

    Författare :Stina Hörnström; [2014]
    Nyckelord :;

    Sammanfattning : Bombardier Transportation in Västerås is developing traction system for trains. These systems must comply with Electromagnetic Compatibility (EMC) standards. Harmonics generated by the traction system is an EMC concern. Better models of the components enables more efficient and accurate prediction of harmonics generated in the traction system. LÄS MER

  3. 3. Design of Highly Linear Sampling Switches for CMOS Track-and-Hold Circuits

    Uppsats för yrkesexamina på grundnivå, Linköpings universitet/Institutionen för systemteknik

    Författare :Muhammad Irfan Kazim; [2006]
    Nyckelord :Switch non-linearities; Bootstrap switch; Bulk-effect compensation switch; Charge injection;

    Sammanfattning : This thesis discusses non-linearities associated with a sampling switch and compares transmission gate, bootstrapping and bulk-effect compensation architectures at circuit level from linearity point of view for 0.35 um CMOS process. All switch architectures have been discussed and designed with an additional constraint of switch reliability. LÄS MER
