1. On Control of Permanent-Magnet Synchronous Motors in Hybrid-Electric Vehicle Applications
Sammanfattning : This thesis deals with design and analysis of the control system structure for electric drives equipped with permanent-magnet synchronous motors with a salient rotor. The intended application is propulsion in electric- and hybrid-electric vehicles. LÄS MER
2. Efficiency of building related pump and fan operation - Application and system solutions
Sammanfattning : The electric energy use in Swedish non-industrial buildings is 71 TWh per year out of which 30 TWh per year is used for the operation of technical systems. A significant part of those 30 TWh/year is used for pump and fan operation. The Swedish parliament decided in 2009 on a national energy and climate plan. LÄS MER
3. Integrated Compact Drives for Electric and Hybrid Electric Vehicles
Sammanfattning : To develop more competitive solutions, one of the trends in the development of drive systems for electric and hybrid electric vehicles (EVs/HEVs) is to integrate the power electronic converter and the electric motor. This thesis aims to investigate the performance and the operation of modular converters in integrated motor drive systems for EVs/HEVs. LÄS MER
4. Power Control Systems in a Flywheel based All-Electric Driveline
Sammanfattning : Flywheel systems are attractive in hybrid and electric vehicles due to their ability to handle power during acceleration and braking. The combination of a flywheel device with a battery source has several advantages such as high peak power capacity, high energy density and reduction in the number of charge/discharge cycles of the battery.

5. On design methods for mechatronics : servo motor and gearhead
Sammanfattning : The number of electric powered sub-systems in road-vehicles is increasing fast. This development is primarily driven by the new and improved functionality that can be implemented with electro-mechanical sub-systems, but it is also necessary for the transition to electric and hybrid-electric drive trains.
