  1. 11. Study of an Isolated and a Non-Isolated Modular DC/DC Converter : In Multi-Terminal HVDC/MVDC grid systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ranjithh Raj Ram Prakash; [2019]
    Keywords : High power high voltage DC-DC converter; Isolated non-isolated DC-DC converter; HVDC MVDC interconnection; HVDC HVDC point-to-point link; Modular multilevel converter; Transformer driven MMC; Steady state transient DC fault analysis; High Power DC DC-omvandlare med hög spänning; Isolerad och icke-isolerad DC-DC-omvandlare; HVDC MVDC-anslutning; HVDC HVDC-punkt-till-punkt-länk; Modulär multilevelomvandlare; Transformatorstyrd MMC; Stabilitet DC felanalys;

    Abstract : För sammankoppling av multi-terminala HVDC-system med punkt-till-punkt kopplingar ärDC-DC-omvandlaren den enda möjliga sammankopplingen. Därför genomgår problemenmed spänningsmatchning och likspänningsströmbegränsning i högspännings DC-systemomfattande forskning samt ligger i fokus för denna avhandling. READ MORE

  3. 12. RANS simulations and dispersion models for particles in turbulent flows

    University essay from KTH/Mekanik

    Author : Li Xiang; [2019]
    Keywords : ;

    Abstract : The aim of the thesis is to evaluate the effectiveness of stochastic models for particles distribution in complex turbulent flow. Turbulent two-phase flows exist in numerous natural phenomena and industrial systems, and remain a very challenging process to describe. READ MORE

  6. 15. A Reconfigurable Device for GALS Systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Rocco Sciaraffa; [2018]
    Keywords : FPGA; GALS; asynchronous; coarse-grained; NoC; bundled-data; FPGA; GALS; asynkron; Coarse-Grained Reconfigu- rable; NoC; bundled data kommunikation;

    Abstract : Globally Asynchronous Locally Synchronous (GALS) Field-Programmable Gate Array (FPGA) are composed of standard synchronous reconfigurable logic islands that communicate with each other via an asynchronous means. Past research into fully asynchronous FPGA has demonstrated high throughput and reliability adopting dual-rail encoding. READ MORE
