Research Abstract

To develop high quality power supply, we have to overcome some difficulties. Magnetic devices such as inductors and transformers are key devices for the development. To apply magnetic devices more actively to power supplies, we have to study their physical performance deeply. In this study, the magnetic properties of ferrite, used for the core of magnetic devices, are clarified and the physical model describing the properties has been developed.
