  1. 11. Vibration analysis of a fast response brushless excitation system

    University essay from Uppsala universitet/Elektricitetslära

    Author : Emma Pålsson; [2019]
    Keywords : vibrations; frequency analysis; FRBE; controlled rectification; hydropower; exciter; generator; fast response;

    Abstract : The aim of this study is to measure and analyze vibrations on a fast response brushless exciter (FRBE) at a real hydropower plant and identify vibration origins through frequency analysis. Moreover, the observed vibrations are evaluated in relation to generator vibration standards and estimated tangential eigenfrequencies of the studied FRBE. READ MORE

  3. 12. Savonius wind turbine innovation integrated in a constructed nano grid system

    University essay from

    Author : Oskar Andersson; [2019]
    Keywords : ;

    Abstract : A nanogrid system for supplying neutrino detectors on Antarctica with electricity is designed and built. The nanogrid system could later on be implemented in various configurations where suppling electricity to neutrino detectors is one area of use. READ MORE

  4. 13. A Study on Interface Circuits for Piezoelectric Energy Harvesting

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Tang Honghao; [2018]
    Keywords : interface circuit; PEH system; switch;

    Abstract : A piezoelectric energy harvesting (PEH) system can harvest electrical energy from ambient vibration energy. In a PEH system, the interface rectifier circuit is critical because it converts AC from the output of piezoelectric harvester to DC that can power the load. READ MORE

  5. 14. Trainable Activation Functions For Artificial Neural Networks

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Jim Öhman; [2018]
    Keywords : ANN; ARTIFICIAL NEURAL NETWORKS; ACTIVATION FUNCTIONS; REGULARIZATION; Science General;

    Abstract : Artificial Neural Networks (ANNs) are widely used information processing algorithms based roughly on biological neural networks. These networks can be trained to find complex patterns in datasets and to produce certain output signals given a set of input signals. READ MORE

  6. 15. Construction of an Active Rectifier for a Transverse-Flux Wave Power Generator

    University essay from KTH/Elkraftteknik

    Author : Olof Brandt Lundqvist; [2017]
    Keywords : ;

    Abstract : Wave power is an energy source which could make a decisive difference in thetransition towards a more sustainable energy sector. The growth of wave powerproduction has however not been as rapid as the growth in other renewableenergy fields, such as wind power and solar power. READ MORE
