Recently, there has been a growing trend toward reducing society's carbon footprint. In the field of energy, clean power generation systems, such as solar and wind generators, have been promoted. In the automotive industry, electric vehicles are also replacing petrol vehicles, and energy-saving electrical appliances are in demand more than ever. Due to this trend, small and powerful power-supply devices with better conversion efficiency are increasingly demanded, and accordingly, high performance inductors are strongly required. In this study, soft magnetic powder cores, which are made by compacting soft magnetic powder coated with insulating film, were successfully improved to be applied into such inductors. The advantageous properties of the developed material are reported, and evaluation results of applying them into inductors are also reported.
