  2. 1. Operation and control of cascaded H-bridge converter for STATCOM application

    Author : Ehsan Behrouzian; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modular Multilevel Converters MMC ; STATCOM; FACTS.; cascaded H-bridge converters;

    Abstract : In the last decade, particular attention has been paid to the use of Modular Multilevel Converters(MMC) for grid applications. In particular, for STATCOM applications the phase leg ofthe converter is constituted by a number of single-phase full-bridge converters connected incascade (here named Cascaded H-Bridge, CHB, converter).

  4. 2. Modeling and Design of Modular Multilevel Converters for Grid Applications

    Author : Kalle Ilves; Hans-Peter Nee; Rainer Marquardt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modular multilevel converter; feed-forward control; modulation; switching frequency; energy storage;

    Abstract : This thesis aims to bring clarity to the dimensioning aspects and limiting factors of the modular multilevel converter (MMC). Special consideration is given to the dc capacitors in the submodules as they are a driving factor for the size and weight of the converter. READ MORE

  5. 3. Battery Integrated Modular Multilevel Converter Topologies for Automotive Applications

    Author : Arvind Balachandran; Lars Eriksson; Tomas Uno Jonsson; Torbjörn Thiringer; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Electric vehicles are rapidly developing in response to the need for increasing sustainable energy sources. The range and lifetime of an electric vehicle are limited by the battery pack. A pack comprises modules with several parallel and/or series-connected cells. READ MORE

  6. 4. On control of cascaded H-bridge converters for STATCOM applications

    Author : Ehsan Behrouzian; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cascaded H-bridge converters; FACTS.; Modular Multilevel Converters MMC ; STATCOM;

    Abstract : Cascaded H-bridge (CHB) converters are today considered the industrial standard for STATCOM applications, mainly due to their small footprint, high achievable voltage levels, modularity and reduced losses. However, there are still areas of research that need to be investigated in order to improve the performance and the operational range of this converter topology for grid-applications. READ MORE

  7. 5. Investigation of a Multilevel Inverter for Electric Vehicle Applications

    Author : Oskar Josefsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plug-in Electric Vehicle PEV ; Electric Vehicle EV ; LiFePO4.; Integrated Charger; Efficiency; Drive Cycle; Battery modelling; Multilevel Inverter MLI ; Two-level Inverter TLI ;

    Abstract : Electrified vehicles on the market today all use the classical two-level inverter as the propulsion inverter. This thesis analyse the potential of using a cascaded H-bridge multilevel inverter as the propulsion inverter. READ MORE
