1. Continuously Variable Split-Power Transmissions with Several Modes
Sammanfattning : A continuously variable transmission (CVT) of split-power design consists of a variator and an arrangement of planetary gears. A black box model describing such transmissions is presented. The model can be used for synthesis as well as loss-free analysis of split-power CVT concepts in general. LÄS MER
2. Study of Induction Machines with Rotating Power Electronic Converter
Sammanfattning : This thesis investigates a novel induction machine topology that uses a rotating power electronic converter. Steady-state and dynamic performance of the topology is studied to understand its operational principle. Furthermore the potential of improving its efficiency and power factor is investigated.

3. A permanent magnet synchronous motor for an electric vehicle - design analysis
Sammanfattning : This thesis presents the study and the design analysis of apermanent magnet synchronous motor (PMSM) for the tractionapplication of an electric vehicle. An existing inductiontraction motor for an electric forklift benchmarks the expectedperformances of the proposed PMSM design. LÄS MER
4. High Speed (MHz) Switch Mode Power Supplies (SMPS) using Coreless PCB Transformer Technology
Sammanfattning : The most essential unit required for all the electronic devices is the Power Supply Unit (PSU). The main objective of power supply designers is to reduce the size, cost and weight, and to increase the power density of the converter. LÄS MER
5. Combustion of gasified biomass: : Experimental investigation on laminar flame speed, lean blowoff limit and emission levels
Sammanfattning : Biomass is among the primary alternative energy sources that supplements the fossil fuels to meet today’s energy demand. Gasification is an efficient and environmental friendly technology for converting the energy content in the biomass into a combustible gas mixture, which can be used in various applications. LÄS MER
