Abstract: Polymer bonded magnetic materials offers many advantages compared to the conventional type of magnetic materials including shape, physical property and cost. This is a new type materials will form a new era of power conversion and is also a new area of research. Until today, no research has been reported on use of polymer bonded magnetic materials. This research studies the method of fabricating a micro-powder filled magnetic polymer composite, its magnetic property and electric property. The paper also describes the application in higher frequency power conversion. A phase-sifted converter using self-resonance which is especially useful for transformer constructed from the low permeability material was used to examine the core. A flyback converter is also used to confirm the use as a coupled inductor. Measured characteristics of the materials and the power conversion measurement data confirm the feasibility of the proposed materials.
