    Abstract : Hydrogen has been identified by the European Commission to be a competitive alternative to fossil fuels within the transport sector in the medium to long perspective. Because of this, an increased understanding is required of the electrical power train present within such vehicles. READ MORE

  4. 3. Comparative Analysis of Several Designs of Modular Multilevel Converters with Interleaved Half-Bridge Submodules

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

    Author : Lingyu Chen; [2022]
    Keywords : Modular multilevel converters MMC ; interleaved half-bridge submodule; interleaved converters; power loss calculation; converter efficiency; converter dimensions; Modulära multilevel-omvandlaren; interfolierad halvbrygga submodul; interfolierade omvandlare; effektförlustberäkning; omvandlareffektivitet; omvandlardimensioner;

    Abstract : The Modular Multilevel Converter (MMC) is one of the most commonly used active converters in the high-/medium-voltage sector due to its many advantages such as high scalability, high efficiency, modularity and low harmonic contents. However, in low-voltage and high-current applications, classical MMC designs are not very economical. READ MORE
