  1. 1. Pre-study of optical LED units for shunting signals

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Tobias Adolfsson; Axel Dellenby; [2021]
    Nyckelord :LED - Light Emitting Diode; Booster Converter; MLCC - Multi-layer capacitor; ESR - Equivalent Serie Resistance; OU - Optical Unit; Reactive compensation; LED - lysdiod; step-up omvandlare; MLCC - flerskiktskeramisk kondensator; ESR - ekvivalent serie motstånd; OU - optiskt enhet; reaktiv kompensering;

    Sammanfattning : Alstom wanted to investigate the possibility of adapting its light emitting diode (LED) technology for shunting signals in train traffic. The LED technology uses 50V, but Alstom wants to adapt it for 12V. The LED technology is energy efficient but needs to be adapted for existing signal interlocking by drawing a higher current.

    Sammanfattning : With climate change threatening life, countries worldwide have united to limit the damages generated by humanity to the world. For a sustainable future, it will be essential to utilise energy in more ecient ways. Energy harvesting in the form of renewable resources and innovative solutions for industries are some answers to an improved tomorrow. LÄS MER

  4. 3. Automatically measuring the losses of a transformer

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för signalbehandling

    Författare :Murad Junaydin Mohamed; [2016]
    Nyckelord :;

    Sammanfattning : This thesis is an ongoing project of Alstom Power Sweden AB, Växjö with a collaboration of Blekinge Institute of Technology [BTH] to automatically measure the losses of a transformer. So far the company performed the measurements manually to get this loss, and they decided to automatize the measurement process. LÄS MER
