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

5. Quasi Resonant DC Link Converters - Analysis and Design for a battery Charger Application
Abstract : Environmental aspects have during the last years made electric vehicles an interesting competitor to the present internal combustion engine driven vehicles. For a broad introduction of pure electric vehicles, a battery charging infrastructure is deemed necessary. However, to build and maintain such an infrastructure is costly. READ MORE
