1. Highly-Efficient Energy Harvesting Interfaces for Implantable Biosensors
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. Control and Design Aspects of Components and Systems in High-Voltage Converters for Industrial Applications
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. On control of cascaded H-bridge converters for STATCOM applications
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. Operation and control of cascaded H-bridge converter for STATCOM application
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).
