Abstract

This paper presents a new type of a polymer bonded soft magnetic material (PBSMM) which can be used to create complex magnetic core geometries. The PBSMM consists of two separate materials, manganese zinc ferrite powder and polydimethylsiloxane (PDMS) as matrix material. The magnetic core losses of the PBSMM where analyzed at 10 kHz and 1 MHz with self-fabricated toroidal core samples by using a custom-made measurement setup in accordance with the IEC-62044-3 norm. The complex permeability was determined by evaluating impedance analyzer measurements between 10 kHz and 1 MHz. It is pointed out that the investigated material can be used for power electronic filter applications and opens the opportunity to create geometrical complex inductive components.
