This research area comprises development of theory, methods and tools for electric power components including magnetic and other materials.
The governing approach is to model material related electrotechnical phenomena and processes by use of Maxwell’s equations and material algorithms in a systems perspective.
The research in this project aims at development of theory, methods and tools for electric power components including magnetic and other materials.
Since the middle of the 80’s a number of activities have been in progress regarding characterization and modelling of apparatuses and systems comprising magnetostrictive and magnetic materials. That work has been focused on characterization and modelling of magnetic materials.
Since the middle of the 90’s the activities also include modelling of transformers, electromechanical actuators and power electronics, electromachines and magnetic amplifiers for aircraft applications.
A magnetic and materials modelling laboratory has been built up around characterization of magnetic and functional materials. The outcome of these measurements is stored in databases and thereafter used as input to computer algorithms included in simulation programs. These programs are finally aimed at helping engineers and scientists in electrotechnical design projects.
The activities within the project comprise:
Applied giant magnetostriction
Design tools and experimental methods
Modelling of medium frequency power transformers in high power converters
In-line hardening of steel components by induction heating
New electrical components for aircraft
The research has resulted in more than 80 publications.
