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

    University essay from KTH/Hälsoinformatik och logistik

    Author : Tobias Adolfsson; Axel Dellenby; [2021]
    Keywords : 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;

    Abstract : 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.

  5. 4. Smart and flexible capacitor charger for warm environments

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Tobias Rydberg; [2016]
    Keywords : ;

    Abstract : A studio camera flash system being developed by Eascal AB needs a capacitor charging power supply (CCPS) that can work in a hot environment without problems and also not emit too much heat itself. The CCPS needs to be able to operate from battery power as well as net power, so called off-line, and to charge a capacitor to between 0-400 V. READ MORE

  6. 5. Combining Solar Energy and UPS Systems

    University essay from KTH/Tillämpad termodynamik och kylteknik
