1. Highly-Efficient Energy Harvesting Interfaces for Implantable Biosensors
Sammanfattning : 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. LÄS MER
2. Pulse and hold switching current readout of superconducting quantum circuits
Sammanfattning : Josephson junction qubits are promising candidates for a scalable quantum processor. Such qubits are commonly manipulated by means of sequences of rf-pulses and different methods are used to determine their quantum state. LÄS MER
3. Control and Design Aspects of Components and Systems in High-Voltage Converters for Industrial Applications
Sammanfattning : 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. LÄS MER
4. On Design of a Compact Primary Switched Conversion System for Electric Railway Propulsion
Sammanfattning : In this thesis, a compact and light primary switched conversion system for AC-fed railway propulsion is investigated. It is characterized by soft switching of all converter stages and a source commutated primary converter comprising series connected valves. LÄS MER
5. Quasi Resonant DC Link Converters - Analysis and Design for a battery Charger Application
Sammanfattning : 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. LÄS MER
