Abstract

This research project is investigating the application of Soft Magnetic Compounds (SMC) in power electronic systems. These materials got the possibility to form free moldable core geometries, similar to the injection molding method. Thereby any available space for complex inductive components can be used. The work involves the fabrication of SMC-ringcores consisting of different soft magnetic powders (e. g. Manganese-Zinc-Ferrite or Ferrite-Copper-Niobium-Silicium-Boron) with variable main particle sizes. Furthermore the influence of the main particle size and their size distribution at the magnetic properties will be investigated. A new measurement System is designed and constructed in order to characterize the ringcores with high precision in dependency of the frequency, e. g. core losses, permeability and saturation. Based on the measurement results the theoretical foundations have to be verified, simulation models forecasting the permeability of SMC´s will be constructed and new fields of applications have to be developed.
