  1. 1. Analogue Circuit for Detection of Ageing Phenomena in Electric Drives

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

    Författare :Yudong Lin; [2023]
    Nyckelord :Electric Drives; Ageing Process; Pulse-Width Modulation; Ringing Current; Peak Holder; Analogue Circuits; Elektriska drivsystem; Åldringsprocess; Pulsbreddsmodulering; Ringningar i strömmen; Toppvärdesdetektor; Analog krets;

    Sammanfattning : This master thesis presents an analogue peak holder circuit design aimed at facilitating the non-invasive inspection of the ageing process in electric drives. The ageing process of electric drives is a crucial aspect that demands accurate monitoring to ensure their long-term performance and reliability. LÄS MER

  2. 2. SIGNALERINGSSTRÄCKA VID KORSNING MELLAN LIDINGÖBANAN OCH SÖDRA KUNGSVÄGEN : KAN VÄNTETIDEN FÖR BILTRAFIK FÖRKORTAS?

    Kandidat-uppsats, KTH/Transportplanering, ekonomi och teknik

    Författare :Tina Alvelöv; [2018]
    Nyckelord :;

    Sammanfattning : Since the refitment of Lidingöbanan which was completed in 2015, the barrier time for car traffic at level crossings have been protracted. In Skärsätra, where Lidingöbanan crosses Södra Kungsvägen and traffic flows are high, this is a particularly big problem. LÄS MER

  3. 3. A parametric approach to data cleaning of ion current measurements

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Fredrik Andréen Blomdell; [2017]
    Nyckelord :Ion current measurements; Data cleaning; Coil ringing; Mathematics and Statistics;

    Sammanfattning : In this thesis, a few possible methods to clean nuisance signals from ion current measurements are explored. Ion current measurements can be used to optimise a combustion engine, but interference from the ignition system coupled with clipping caused by limitations in the measurement equipment limit the amount of data that can be extracted.

  4. 4. Ion current interface

    Kandidat-uppsats, Institutionen för systemteknik

    Författare :Morgan Johansson; [2005]
    Nyckelord :;

    Sammanfattning : Abstract Abstract The reason to measure the ion current in a combustion engine is to extract combustion parameters in order to achieve closed loop control of the combustion i.e. control of the spark, fuel and air into the engine. By using the spark plug, in a spark-ignited engine, as a probe it is possible to measure the ion current. LÄS MER
