  1. 1. Highly-Efficient Energy Harvesting Interfaces for Implantable Biosensors

    Author : Janko Katic; Ana Rusu; Saul Rodriguez; Gabriel Rincón-Mora; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy harvesting interface; thermoelectric generator; glucose biofuel cell; power management; dc-dc converter; boost converter; zero-current switching; zero-voltage switching; implantable biosensor; Energiskördsgränssnitt; termoelektrisk generator; glukosbiobränslecell; energihantering; DC-DC-omvandlare; boost-omvandlare; inplanterbar biosensor; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Energy harvesting is identified as an alternative solution for powering implantable biosensors. It can potentially enable the development of self-powered implants if the harvested energy is properly handled. This development implies that batteries, which impose many limitations, are replaced by miniature harvesting devices. READ MORE

  2. 2. Control and Design Aspects of Components and Systems in High-Voltage Converters for Industrial Applications

    Author : Per Ranstad; Hans-Peter Nee; Alfred Rufer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-voltage converter; resonant converter; high-voltage transformer; transformer parasitics; IGBT; soft-switching; control; Electric power engineering; Elkraftteknik;

    Abstract : High-frequency dc-dc converters are widely used in power electronic applications, both in consumer products and industrial products. By operating the converter at higher frequencies both a smaller size and better control characteristics can be obtained. READ MORE

  3. 3. 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

  4. 4. 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).
