Characterisation of a Ferrite-Polymer Based Magnetic Material

The design of highly integrated converter is more than ever a hot topic in the power electronic world. Integration also brings new challenges and opportunities for magnetic design, e.g. use of new magnetic material or innovative manufacturing process. This paper is presenting the manufacturing process and characterisation of a composite material applied to the design of a magnetic components which is fully compliant with the printed circuit board (PCB) process. This paper is presenting results of the charac-terisation on the ferrite powder and on the soft magnetic compound (SMC), some insight are given on the material manufacturing before presenting additional characterisation procedures, especially for core losses measurements.
