  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. On High-Speed Digital-to-Analog Converters and Semi-Digital FIR Filters

    Author : Mohammad Reza Sadeghifar; J Jacob Wikner; Robert Hägglund; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DAC; RFDAC; SDFIR; FIR; semi-digital FIR filter; digital-to-analog converter; D A converter; data converter; mixed-signal integrated circuits; mixer DAC; IQ modulator; transmitter;

    Abstract : High-speed and high-resolution digital-to-analog converters (DACs) are vital components in all telecommunication systems. Radio-frequency digital-to-analog converter (RFDAC) provides high-speed and high-resolution conversion from digital domain to an analog signal. RFDACs can be employed in direct-conversion radio transmitter architectures. READ MORE

  5. 3. Cascaded Converters with Gate-Commutated Thyristors : Experimental Verification and Auxiliary Power Supply

    Author : Tomas Modeer; Hans-Peter Nee; Staffan Norrga; Dragan Jovcic; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis describes an effort to investigate the use of gate-commutated thyristors(GCTs) in cascaded converters. Cascaded converters, such as modularmultilevel converters (M2Cs) and cascaded H-bridge converters (CHBs), haveproved to be especially suitable in high-voltage, high-power applications. 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. 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
